Dan,
There is actually quite a nice variety of things within a 10-15 minute drive of Matteson. Here are a few of them, Sdritz also is in the area and can add several other places.
In nearby Olympia Fields, I have had some very nice meals at Burgundy Bistro.
www.burgundybistro.com . Across the street from there is Flavor restaurant which has very good brunches on weekend, and live jazz on some weeknights
www.flavorestaurant.com . Next door to that is Siam Thai which has very reasonably priced Thai cuisine (it is not in the caliber of the places in the City though).
Tinley Park is also a 10-15 minute drive, and you can spend quite a bit of time just trying and enjoying the very good Italian joints there. My personal favorite is Isabella Cafe (
www.isabellacafe.com) which is located in a wonderfully romantic setting, and the Roasted Lamb Shank is tremendous. G-In is a Korean owned Japanese place that is in my regular rotation. Tin Fish is highly regarded for seafood, though I don't think it is very conversation friendly
In the H-F area, Flossmoor Station has some very good brews, and fair pub food. Sdritz could also tell you how Bamboo Blue is these days, I haven't been in a couple of years.
Mr. Benny's in Matteson is a nice "old school" steakhouse as mentioned in one of the threads Cathy links to.
If there are any specific types of food you are looking, let me know.
