They have a section that's free seating. I've been there a few times without a reservation and not had a wait. But if you have a large party, any more than 4 I'd recommend a reservation. It does get busy on the weekends.
I've always called 10 to 15 minutes before getting there and never had a problem.
Depending on the time of day better to reserve if you are a large group
It's better to reserve because it might be crowded.
