Good traditional diner food. Reasonably priced, very nice staff, and some special orders didn't phase them. My daughter is at U of I and we came down for a football game. I would absolutely go back in the future.

Styled a lot like a 50's diner, serving a variety of burgers, chicken, or fish & chips this is almost a throwback. The burgers a huge and the fries are really tasty with a golden crunch but still tender inside. A wonderful little adventure place.

As an amateur powerbuilder with the appetite of a small bear preparing for hibernation, I take portion sizes very seriously. Most restaurants leave me wondering if the entrée was actually the appetizer. Not Jack Jack's. The portions here are fantastic for the price, and I always leave full and satisfied without feeling like I need to stop for a second …

No wonder it's a local's favorite! Great service and good food! Desserts are made in house, too. That chocolate silk pie is thick and chocolaty. Thoroughly enjoyed dinner. We'll be back for more meals.
