Diamond Jo Casino Dubuque is a Boyd Gaming casino and entertainment complex in Iowa’s Port of Dubuque, with more than 700 slots, table games, a retail sportsbook, dining, bowling, and live entertainment. Its strongest selling point is the ability to build an evening around more than gambling. I’d shortlist it for a group outing or a casino stop during a Dubuque weekend. The main limitation: there’s no on-site hotel, so overnight visitors need separate lodging.

What kind of casino is Diamond Jo?
Think evening-entertainment complex rather than casino resort. You can pair casino time with a steakhouse dinner, bowling, or a scheduled show. What you cannot do is take an elevator to your hotel room when the evening ends.
That distinction matters more to me than a few machines either way. A group with different interests can make good use of the bowling and entertainment, while someone planning an overnight gambling trip must arrange lodging and the return journey separately.

Casino floor, slots, and table games
The Iowa Racing and Gaming Commission’s facility listing puts Diamond Jo’s gaming floor at 41,408 square feet, with 704 slot machines and 22 table games. These are published inventory figures, not a promise that every machine or table will be available when you arrive.
Boyd’s property fact sheet lists 18 table games rather than 22. The practical picture is still a regional casino with a substantial machine selection and a smaller table-game component, not a sprawling destination-resort floor.
Slots and video poker
Approximately 700 slots is the useful planning figure. Particular titles, denominations, and progressives can change, so I would not make a special drive based solely on a remembered machine lineup.
Check the total wager before pressing the button. A small denomination on the cabinet does not necessarily mean a small bet. If video poker is your priority, ask about the current selection and inspect the paytable rather than assuming a familiar game name means familiar payouts.
Win-and-loss stories do not establish machine value. Set a gambling budget, and keep dinner, tickets, and the ride home outside it.
Table games and minimum bets
Blackjack is specifically identified in Boyd’s fact sheet, including high-limit blackjack in the VIP Lounge. Call ahead if another particular game is the reason for your trip; a table count is not a complete game roster.
I would not budget around an advertised or remembered bargain minimum without checking. Read the posted limits and rules before buying in, and remember that individual tables can have shorter schedules than the casino itself.
Poker room
Diamond Jo Casino Dubuque has no dedicated player-versus-player poker room. Video poker and poker-themed dealer games are not the same as a cash-game or tournament room.
Diamond Jo Sportsbook
Diamond Jo has an on-property retail sportsbook, listed by the state regulator as Diamond Jo Sportsbook and operated by Diamond Jo, LLC. Boyd describes the space as 2,150 square feet with 34 television screens.
For a sports bettor, that provides a place to work a game into the evening rather than following it only on a phone. Check staffed-counter hours and ticket-redemption arrangements before visiting. Keep paper tickets secure, and understand how to collect winnings if you leave town before an event finishes.
Hotel: overnight visitors need separate lodging
Diamond Jo Dubuque does not have an on-site hotel. That is its biggest practical difference from a full casino resort.
Compare the complete hotel bill rather than the headline room rate. Parking, breakfast, fees, and transportation can change which booking makes sense. Check the route back from the casino, especially if you expect to return late or in poor weather.
Do not count on a complimentary shuttle unless your hotel confirms the service and its hours. If the plan includes drinks, arrange your return transportation before the evening starts.
Restaurants and bars
Boyd’s Diamond Jo Dubuque fact sheet describes three dining choices:
- Woodfire Grille: The steakhouse-style option, with USDA Prime steaks, seafood, and wine. Choose it when dinner is part of the occasion rather than a quick casino break.
- The Game Sports Bar: Burgers, sandwiches, drinks, and wall-to-wall televisions for visitors pairing a meal with sports viewing.
- The Filament: A casual pub-style option near the eastern entrance, described as offering more than 20 beers on tap.
My advice is to choose the meal first, then fit gambling around it. A steakhouse dinner and a quick sports-bar stop require different amounts of time and money.
Confirm the current dining lineup, menus, and kitchen hours. For a special dinner or a meal before a show, ask about reservations. Include drinks, tax, and a tip in your budget.
Cherry Lanes bowling and live entertainment
Cherry Lanes has 30 bowling lanes, while Alley Cat VIP Lanes offers private lanes for parties. That is a meaningful strength for mixed-interest groups: nobody has to keep gambling simply because everyone else wants to stay.
Ask about lane availability, shoe rental, prices, and reservations. Discuss the private-party option directly if you are organizing a group.
Mississippi Moon Bar hosts national and local entertainment and has three levels of seating. Check the individual event listing for ticket prices, seating, door times, and age restrictions. A venue on the property does not mean there is a show every night or that admission is included.
Free parking, directions, and visit costs
Use 301 Bell Street for the casino. For parking, the useful address is 351 Bell Street, the adjacent Port of Dubuque Parking Ramp. The City of Dubuque lists the ramp as free, with access from Bell Street and East Fourth Street. It also lists free public parking at Fifth and Bell and Third and Bell, available around the clock.
I would start with those Port parking options rather than automatically choosing a paid downtown ramp. For an illustrative four-hour visit, the Intermodal ramp’s published $1.00 hourly rate produces a $4.00 bill, versus $0.00 at the adjacent Port ramp. At the Intermodal ramp’s published daily cap, the difference is $10.00. This compares municipal parking choices, not a casino parking charge or rewards-card benefit.
Gamboool original analysis
We assembled the comparison below from published information and our calculations. These are selected examples, rather than measured gambling sessions or a representative survey.
| Detail | Published information |
|---|---|
| Port of Dubuque Parking Ramp: Location, price, and access | The city lists free parking at 351 Bell Street, adjacent to Diamond Jo, with access from Bell Street and East Fourth Street. |
| Port of Dubuque public parking: Free alternatives and availability policy | The Port ramp and the lots at Fifth and Bell and Third and Bell provide free public parking around the clock. |
| Intermodal Parking Ramp: Paid alternative and payment methods | This municipal alternative charges $1.00 per hour, capped at $10.00 daily. Exit payment accepts credit cards, while the elevator-lobby payment station accepts cards and cash. |
| Downtown Dubuque parking meters: Enforcement and rate comparison | Meters are enforced Monday through Saturday from 8 a.m. to 5 p.m. Shorter-limit meters charge $0.25 per 20 minutes; 10-hour meters charge $0.25 per 30 minutes. |
| Downtown Dubuque metered spaces: Saturday payment requirement | Unlike the free Port parking options, metered spaces require payment during Saturday enforcement hours. |
| Iowa Street Parking Ramp: Public-access restriction during construction | The city lists this ramp as permit-only, with no public parking during construction from mid-September 2025 through 2026. |
| Diamond Jo Casino Dubuque: On-site lodging inventory | The state regulator lists no hotel rooms, so an overnight visitor needs separate lodging rather than an on-property room. |
| Cherry Lanes and Alley Cat VIP Lanes: Standard bowling versus private-party option | Boyd’s property fact sheet lists a 30-lane bowling center and a separate private-lane offering for parties; it does not provide booking prices. |
| Calculation | Result | Takeaway |
|---|---|---|
| Illustrative four-hour visit using the paid Intermodal ramp | $4.00 | For this example visit, paid downtown parking adds an avoidable expense: the city lists the Port of Dubuque ramp adjacent to Diamond Jo as free. |
| Illustrative four-hour visit using the adjacent Port of Dubuque ramp | $0.00 | The adjacent public ramp eliminates parking charges for the example visit without requiring a casino promotion or rewards benefit. |
| Published daily parking cap at Intermodal compared with free Port of Dubuque parking | $10.00 | For a stay that reaches the paid ramp’s daily cap, choosing free Port parking preserves more of the outing budget. This comparison concerns municipal parking, not a casino parking fee. |

Method: Published inputs collected 2026-10-16. Illustrative assumptions are labeled, and the full calculation inputs remain in the saved research record. These examples support planning; they do not predict a particular session.
Free parking does not make the whole outing inexpensive. Keep gambling, meals, drinks, bowling, tickets, lodging, and transportation as separate budget items. It is easy to plan a modest casino stop and accidentally purchase a full evening out.
- Bring photo identification: You must be at least 21 to gamble.
- Allow arrival time: Leave time to park and walk before your restaurant reservation or show.
- Ask about accessibility: The city provides accessible spaces in its lots and ramps. Discuss the casino entrance, walking route, and venue seating if those affect your visit.
- Check smoking arrangements: If smoke exposure is a deciding factor, ask specifically about the gaming floor and your route to dining or entertainment.
- Understand rewards before playing: Ask the players desk about current earning rules and offers. A perk is not a good reason to increase your gambling budget.
Who should visit Diamond Jo?
I’d choose Diamond Jo for a Port of Dubuque outing that combines casino time with dinner, bowling, or a scheduled show, particularly when the group does not share one enthusiasm for gambling. Its roughly 700 slots, retail sportsbook, and free adjacent public parking make it a practical regional stop with more to do than play. The meaningful compromise is overnight convenience: visitors who want a room and casino under one roof should choose a property with an attached hotel.
