Let me begin by saying that I've been going to The Smiling Moose for as long as I've lived in the South Side (about 3 years) and I've never have a bad meal. The chef is classically trained and the specials change daily. My tried and true favorite sandwich is the Grilled Chicken, Cream Cheese, Sweet Chili, Red Cabbage, Bacon ($9) that comes with the side of the day. Usually the side is their out of this world macaroni salad. I don't know what their secret is, but it's the best I've ever had. Sweet, savory and slightly spicy. I could eat this alone! I'm also a big fan of their Crostini of Rosemary and Basil, Tomato Salsa, Fresh Farmer's Cheese appetizer. This is like a very fresh and delicious bruschetta without the balsamic. There are options for meat lovers and vegetarians alike.
The atmosphere is great if you are a fan of the "hole in the wall" type establishment and loud music. There is also a small concert venue upstairs so there can be a crowd during a show. There is a large projection screen in the small dining area and quite a few televisions, so this wouldn't be a bad place to grab a beer and a bite during a game.
Bottom line : make sure to give The Smiling Moose a chance, I bet you won't be disappointed!
