I really like the burgers at TnT's in East Peoria. Not sure if the Heights location has the same menu, but they have good burgers and wings.
I do like the fish dinners at Culver's. Growing up in WI, it was THE place to go for fish fry during lent. It was a family owned, local restaurant with a few locations in WI. Now that it is a larger chain, I don't hardly go there. lol. But I do like it. Of course franchising it has changed the food, and the menu but its still good food.
