Yes
Not needed. There is limited reservation spots available. However, without one, the later you wait to go, the longer wait time will be. Have gone at 8 PM and told the was a 3 hour wait (which was closing time)
Reservations are no required, but recommended. If you go during peak hours as a walk in you will probably have a wait.
It is preferred to rsvp but you can walk in. Just watch for peak hours
