I had the Chimmie Chimmie, and it was incredibly good. The flavors and taste are very unique. There are a million sub places in Madison and surrounding areas, but the ones you want to go to are the ones who offer something different, while still being delicious. Chimmies is one of those, and it will be on my short list of places to go when I want a sub. My wife had the Hot Press Roast Beef and she enjoyed it as well. I had about a quarter of it, and I thought it was fantastic. The bread was nice and flaky but fluffy on the inside like a good hot press sandwich should be.
The fries that came with my Chimmie tasted almost exactly like McDonalds fries. Which isn't bad, because they're pretty well known and liked. We've never actually run across fries that tasted so close to them before.
While a bit more expensive than most places by a few dollars, you do get a full meal out of it, and again, the taste of the sandwiches is unique which is the most important thing in my book.
