I've been to Sandwich box a few times, usually on the insistence of my friends. Chicken Parm loves the Box, for sure. I must say, it's good, even great. Certainly, one of the best places to get a sandwich, especially a gourmet sandwich, in the city. I just feel it's a bit overrated.
Basically the concept is this: you pick the bread, you pick the meat, you pick the spread, you pick the toppings. Also, the bread, meat, spread and topping options are all of stellar quality. It's a simple and terrific concept and works very well. But...it's not very big and sometimes they're less than generous with the toppings.
I suppose the new location was chosen because it's meant to be larger but the way they've got things set up it seems as crowded as ever. Though now there are places to sit and eat which is a huge plus.
I'd give it 5 stars if it was either way bigger or way cheaper. Still, it's a great sandwich.
