I've always walked by this sandwich shop and wondered why the line up was so long (literally out to the middle of the mall!) After trying a customized sandwich at the urging of my coworker, I now understand why. And in fact, I'm the person getting in line even though I know it's going to be a ten minute wait.
This family-run deli allows you to customize everything about your sandwich (a variety of gourmet breads, meat fillings and up to five vegetable toppings, plus a range of spreads from hummus to avocado to cranberry). The best part is the roasted vegetables as a topping- literally chunks of broccoli, bell peppers and cauliflower with seasoning that they add to the sandwich. I haven't been able to find this topping anywhere else. The sandwiches are made to order in an open kitchen while you wait. My sandwiches usually come out to be two inches high.
As for value, sandwiches average about $7 each (plus tax), but are large and will fill you up.
They also have daily features, and sandwiches are discounted to $5.99 on Fridays. If you are a regular, be sure to ask about their stamp card program.
