No but if you dont have one, you'll be waiting for a long time
While reservations are not required, making one can save a considerable amount of time. However, it is all about timing. You could be seated immediately, but chances are there is going to be a wait.
Its best to download the app and get a reservation but i have been able to walk in and be sat quickly. But almost never during the "typical" dinning hours. 11-1 5-7pm. You could wait up to an hour.
Not essential, butI would recommend especially in the evening.
