No reservations necessary. It's walk-in when it's not busy. During busy times, the host/ess will take your name in the order you come in. It may look like an impossibly long wait, but they turn over tables quickly.
It is first come first served and it is popular so you can wait during the usual busy weekend times
We were walk-ins, so no experience with reservation, and I would predict first come first served
First come
My experience has been it's first come, first served.
