Good Restaurant near O'Hare, please advise
I don't know if you're from Chicago or not but there are so many good restaurants in the area. One that comes to mind that would be good for out of towners is Harry Caray's on Higgins just north of the airport off of River Road. You can call 847-699-1200. in the same area is Nick's fishmarket. You can always check here for more http://www.pickarestaurant.com/chicag...
Although Harry Caray's and Nick's might be very enjoyable, neither would be remotely close to your request for "not too expensive, a dive is great". Although I am not sure that it fully fits your description, I have seen great comments on the boards about Rosewood Restaurant - http://www.rosewoodrestaurant.com.
Here are a bunch of recommendations, all within 10 minutes drive of O'Hare:
1. Steakhouses. Black Ram Steakhouse is a restaurant in Des Plaines. All of the food there is absolutely GREAT - the steaks, the seafood, the desserts, everything. It doesn't get a lot of press, but it gets a lot of repeat business. The proprietor greets lots of arriving guests by name. If you're looking for a great steakhouse (and seafood) restaurant that nobody ever heard of, this is it.

Gibson's and Morton's both have locations near O'Hare too, and both are better known. If you're looking for an unsung place with better food, including steaks but particularly if you want something else, I think Black Ram is better, but if you're looking for a famous place that people can brag about having gone, then maybe this is your ticket.

2. Pizza. I think the most impressive and unique specialty in Chicago is our Chicago-style deep-dish pizza. One of the very best is Giordano's, which specializes in a double-crust "stuffed" pizza. You can phone your order ahead of time if you want to avoid waiting 30-45 minutes while seated for your pizza to bake; you can find their menu on their website.
9415 West Higgins Road
3. Flamingo's Seafood - Another place near O'Hare is my very favorite Mexican restaurant in the entire Chicago area (heck, the best Mexican food I've had outside of Mexico). It's called Flamingo's Seafood, in the suburb of Mount Prospect. Open for lunch and dinner seven days a week. They specialize in Mexican seafood dishes, and always have a large number of daily specials in addition to their extensive regular menu. Last time I was there I had a grilled Chilean sea bass with guava habanero sauce and crushed pumpkin seeds that was to die for. Located at Busse Road and Dempster, just north of Algonquin Road. Take I-90 westbound, exit at York Road, go north to Algonquin, and turn left.
