★★★★☆ 4.0 Rob Williams · Dec 2025

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.

★★★★★ 5.0 Jeff · Nov 2025

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
