Been wanting to come here for a long time now! Are walk-ins welcome and you can buy tickets at the door? Or is it recommended to make reservations and buy tickets in advance?

Tickets at the door are fine unless it is a special guest. Check their website.

It's not a big place. I would get the early because it's a first come, first served place and you want a good table up front. If you go early you can probably get tickets at the door but very easy to get them on line.

Yes and yes , call first about reservations
