Tootie's is not gourmet or health food. Tootie's sells 2 types of meat - spicy Italian Beef and Sausage. You can get either on a sandwich or a mix of both. The sandwiches are very dense and meaty which makes up for the fact that a 4" Italian Beef costs more than a Subway footlong. If you get the 12" at Tootie's, you should also invest in a bottle of Tums.
The actual storefront is tiny - with a counter and not much more. Plan to take your sandwiches in a bag to eat in the street or at home.
As others have said, these sandwiches are a good counter-balance to the hot dogs, gyros, and pizza you can get elsewhere in the South Side. So far, I've only had the sandwiches for 2 very filling lunches, but I'm looking forward to enjoying them as late-night drunk food.
Stop in if you're hungry for a filling, juicy, beef sandwich. You won't regret it.
