You can call and make reservations.
They don't take reservations. When you arrive you just add your name to the seating list. They can accommodate large parties but you're best off arriving right when they open or around 6 - 6:30 when the first round of people are finishing up. Often one member of a larger party will go early to get on the list so when everyone else shows up they don't have to wait as long. It's a pretty small space. Thar being said, they are worth the wait!
