Go for Lunch and you'll be back again.
I used to go here daily when I lived around the corner while in college. All of the signature sandwiches that they offer are great, the Red light district is a play on the rubin, but better, the Van Gogh is equally delicious.
If your not in the mood for a sandwich ask them what the soup of the day is, if it's Lemon Chicken and Rice...get it, it's good, you wont be disappointed. You can even get half a sandwich and a soup if you crave both.
