Too much of a good thing.
The review by lisarollins says it better than I could. This place is great. Too great, in fact, becuase there are too many people there during peak times. So stay away! Or go early. And go hungry, as the sandwiches are larger than the average fare elsewhere. No kidding about the options. Curious? Check the menu at http://subdepot.net/. Avoid the green salads. Soups are canned, but usually pretty good. Bonus: you can sub any side for chips in a combo. Only the fruit cup is freshly prepared, the rest are bulk but quite tastey.
Popular with the lunch crowd.
This restaurant has a lot of sandwich options! If you can't find something you like, that's your fault! They do have green salads (McDonald's-level quality) and pasta salads (average), but you should really go for their highly personalizable sandwhiches (they even have avocado on the menu!) and to see their potato chip selection. It gets really crowded at lunch so go early to beat the rush. During prime time, you can wait in line for 10 minutes and wait another 15 minutes to get your food, making your eating and travel time pretty tight. Lots of magazines to read while you wait, however.
