Definitely need reservations... but you should call & see if they can put you on a wait list or something because we had a reservation and I asked to move it up and they called and moved the time up - otherwise go on their website or Open Table and see if they have an opening.
Yes, the place is usually booked weeks in advance and weekends are especially busy. If you get there when they first open sometimes you can sneak in before the primary reservations start.
I believe I made reservations for my wife and I. We ate at the bar area over looking the chef's cooking station. We talked to the chef's and had a great time.
The other time I ate there was with a work group of 6-8 people. It was a week night and we definitely made a reservation.
I hope this information is helpful.
