I know it's probably un-healthy, but I think their sandwiches are pretty delicious. The sandwich hits the spot quit well especially when you're starving for a late lunch around 2pm. What I love are the extra stuff they put on your order (of course they're optional, but I put everything on - I can't do without pickles and jalepeno pepper). I really enjoyed the veggie mushroom sandwich, but i got turned off just a bit when I realized how greasy it looked with the melted cheese .... .
The service is quick. The staff are very friendly. And as everyone mentions, the price is awesome (especially for students).
