As one of the other Yelpers pointed out, it's a similar menu to California Sandwiches...except that the food is much better here. Being a vegetarian I'm a bit limited in my options but I never get sick of their simply outstanding eggplant parm. It's cooked and breaded just perfectly every time. I often find that eggplant is either often too crispy and crunchy or too soggy and rubbery. These guys nail it dead on.
The spice level is just perfect as well...I like mine hot but you have the option of getting it medium or sweet as well. Oh and did I mention that the sandwiches are HUGE and cheap? Five bucks (I add sweet peppers for $.88 extra) for a delicious, large sandwich with cheese included is a bloody steal.
Seriously try them out. The staff is friendly and family members assure me that their meat options are just as good. Highest possible recommendation.
