Do you need reservations for dinner?

I didnt have to make reservations. I was able to sit right down and eat. :)

I'd recommend a reservation if you are going at a peak time. You do not need one, but it'll eliminate any wait they have if you already have a seat saved. I've seen them seat immediately and have as much as an hour and a half wait so it's really up in the air.

I also did not have to make reservations. We walked in on a Saturday about an hour after opening.

I would make reservations if you would like to sit next to the tank. Otherwise if you have no seating preference no reservations needed. We walked right in and were seated.

We just walked in when we were there.
