The potato focaccia will change your life!
It's hard not to get overwhelmed with the choices...so many delicious potential sandwich combos. My personal favourite is pesto, brie, tomato and turkey. The salad on the side is a nice touch. Yes, the sandwiches are $10, but once you taste the melting brie, you will forget any qualms you may have had about the price.
I've also tried the salad bar and the soup. Both are decent, but it's called Sandwich Box for a reason.
One last tip: don't plan to dine-in...the place is usually packed from 11am-1:30pm and it's tough to find a table.
