Its like an upscale diner hiding inside Harringtons casino. The food is fine and they have events on the calendar.

My wife and I dined here for the first time with her friends. From the door, we were welcome well and the atmosphere was amazing. This place is so cozy and we loved it. Lizzie and Emma attended to us and they were friendly and professional. We had bb q rips, prime rip, green beans and some drinks. The was delicious. I recommend this place to all.

Decided to give Onion Jacks a try for the first time, and I have to say I was pleasantly surprised by both the food quality and amazing staff.
The staff from seating to leaving was super attentive and made sure we got exactly what we wanted. Special shout out to Amber for just being the best server I’ve had in 2025! She made stellar recommendations, that ended up being 10/10 !
The food, which was crab cakes (no filler), crab soup, and a shrimp starter all tasted great! Oh also fried ravioli was delicious . Left with a key lime pie, that I couldn’t eat now but sure will later.
If you get a chance give it a try, I bet you will enjoy it.

We chose to grab dinner at Onion Jacks before going to the Jordan Davis Concert, thinking it would be a great start to our night out. Service was extremely slow, please but slow. Our food was okay..Prime Rib with house salad and potatoes, Classic Cheeseburger and fries, Crab Cakes with green beans and potatoes and Taco Salad with grilled chicken. Not sure what we expected but felt like dinner food vs high end pub food. We ordered several of their Signature Cocktails…Stormy Sea, Blue Skies, Cherry Captain and BBQ Smoked Old Fashion had no desire to reorder any of them. We were disappointed with our experience. We would have been better off grabbing Fair food.

Service was great, crab cakes were amazing, NY strip was goid. The Prime Rib, however, was the ABSOLUTE worst I’ve ever had in my life!;. 90% ALL FAT, absolutely disgusting. My dogs will be happy to get a $35 prime rib for dinner

My husband and I went here for the first time for our 10 year anniversary. The setting in this restaurant is very cozy I love it. We had a awesome waitress to go with the awesome food. I ordered the open face turkey sandwich with onion rings it was amazing. The turkey and gravy is served on crispy texas toast. I would not recommend the raspberry tea it was very bland. My husband ordered spaghetti and it came with salad plus garlic bread. I would definitely recommend this spot for girls day/night out,a quick bite,lunch,Date night this place is very versatile. Food is very Affordable as well.

I’ve been going here for years but last week was the worst. My salmon wasn’t cooked fully on my salad. I don’t eat any kind of raw meat nor fish . Matter fact any kind of animal product has to be cooked fully.
My waitress was phenomenal and took it back to be fully cooked all while I prayed that they did nothing to my salmon
I don’t know if they had a new cook or if it was a bad day as I heard the table in front of me say something about their food. I’ll specify next time please fully cook my salmon
I have pictures but don’t see how to post with this review.

Food was good… we got grilled chicken Caesar salad and a classic burger with cheese and onion rings. For adult beverages we originally asked for a margarita and was told the bar couldn’t make that. We were advised to go to the lounge instead. When he didn’t get waited on, and came back empty handed the waitress offered to get one from this bar. Took a while but it was finally delivered and made properly. Also got a captain and ginger ale which was yummy. Overall decent service and good food for the cost.

I wish I could comment on the food or service but the purpose of this review is to make it known that you MUST be 21 since the only way to access this place is thru the casino! Bonz has a seperate entrance why not this place? I didnt see this restriction anywhere and we showed up with a newborn in the group and were denied entrance. Now for the good part, they blame the casino/state for this but I havent had the same problem in the dover casino so no, sorry, try again!
