I recently went back to Illinois and visited East Peoria and Peoria Illinois.
If you are there, I highly recommend eating at these places:
Granite City Food & Brewery a good meal with some interesting appetizers. I highly recommend them. You can see the food at http://www.gcfb.net/
Alexanders The steak I had at this place was amazing. You are in the second story of an old factory, and you can grill your steak, or have one of the chefs grill it for you. It was 23 ounces of heaven. Direct link is http://www.mercedesrestaurants.com/
Flat Top Grill Great time, you select your vegetable, sauce, meat and sides, and then they grill it in an asian fusion style, and bring it to your table. Yum!
Burger Barge The hamburger I had, the Tavern, was amazing. Fried Egg, Ham, Onion on a great roll. We sat outside on a hot day and enjoyed Mountain Dew and Meat. What more can you ask for? Direct Link is http://www.burgerbargeinc.com
This place was worthy of Diners Drive-ins and Dives.
