The O’Fallon location is a great place to eat. They serve large portions. I had fried pickles, strawberry lemonade, chicken strips, and fries.
The servers at JJs give excellent service. They make you feel like family. Diane is awesome always a full beer witty repartee and full service. She is one of the best at JJs and a great, fun person. So ask for Diane you will be happy.
I've always enjoyed the food that I get from here. I especially like their Mucho Nachos and they have delicious cheese curds!
Excellent restaurant. Service was great. Delicious food. Our server, Danielle, was super duper! She handled our large party with many separate tabs very well. She was amazing! Thank you Danielle! I had the pork ribeye, baked potato and salad. My husband had the fried chicken. Both really delicious. My niece is a connoisseur of Reuben sandwiches and she said that her Reuben was one of the best ever. Thank you JJ's. We will be back.
I didn't think I'd like this place at first given the old atmosphere, but it was really charming once my partner and I sat down! The Patty Melt is the best I've ever had. Super juicy! And the Fried Chicken, hands down some of the best I've ever had. The meat is fall-off-the-bone tender and seasoned to perfection. Highly recommend this hole-in-the-wall restaurant. Thoroughly impressed and will come back!
Great lunch spot with large portions of delicious food. The pulled pork nachos easily could feed 3 people. The BLT is piled high with crispy bacon and served on 3 slices of grilled sourdough! The Bosco sticks were hot and fresh.
First time visiting JJ’s stopping in for a late lunch. All the staff were super friendly. Food all was hot and tasty. Large portions that we needed to bring half of it home. Prices very reasonable. Very nice diner atmosphere with plenty of old photos and memorabilia on the walls.
I had lunch with 15 ladies. They put us in our on room so we could visit without distributing the rest of the restaurant. Our waitress was absolutely fantastic. All food came out correctly and at the same time.
I had gone here today for the very first time today! I was truly a great experience. I enjoyed the service. I think my servers name was Marissa Vakro? i think but she was a great server! was very kind and kept checking up on us! I would highly recommend this place!
Awesome food - service - the works! I have had steaks that cost 4x as much that weren’t as good as this! And the price was great too - can’t believe I haven’t stopped in here before! Definitely coming back with the rest of the family!!
