In ranked order of the sandwiches I have tried:
1. Fried Chicken
2. Brisket
3. Pork Belly
4. Hot Roast Beef
5. Cold Turkey
They are all good, but the fried chicken is really, truly delicious. The other sandwiches are good as well, but they have many homemade sauces that they use to top the sandwiches, and sometimes I think the sauce runs away with it and the sandwiches end up being one note. Nevertheless, they are really well made sandwiches, the staff is cool in a conscientious-yet-cool way, and I have always enjoyed everything I have gotten there.
Highly recommended over other popular sandwich chains rhyming with Clubway, Pita Snit or Mr. Bub.
Next to try: the fries.
