Is it necessary to make a reservation for a Sunday?

I would recommend it

I think reservations might be needed as only outdoor seating is available.

On the website it says reservations are highly recommended. We went on Saturday without a reservation and they were able to seat us in a timely manner.

I called Tuesday for a Saturday reservation last week and got one. Would recommend it if you don't want to wait for a while.

I went this last weekend and the menu says reservations are required for sat and sun, they are 10 days out. And walk ins will not be allowed

I highly recommend making one. I showed up without making a reservation and the wait was 45 minutes.
