You don't need to, but it gets pretty busy. Better to make a reservation in my opinion
Reservations are not required but recommended.
Definitely recommend that you make a reservation. I've used Open Table in the past: https://www.opentable.com
I agree with Jarom. Best to make a reservation. I eat here a few times per month and it gets crazy around 11:45am-1:30pm and then again from 6pm-8:30pm. If you're going outside those hours, you'll probably be fine. But if you want to be seated during those hours, without a minimum 30min wait... You'll want a reservation.
