This Submarina is different from the other franchises I have tasted. When you walk into the San Marcos location, you can't help but feel that you are at someone's house. The stye of decor adds to this home-like feel. The employees appear to be family are very friendly and quick at making your sandwich.
My favorite time to go is anytime but lunchtime (they get really busy). I like getting their 3-inch specials with a cup of chili. It's a great deal and is delicious.
