Do they do walk ins? Or have to make a reservation?

Walk ins are fine. Ask to tour the kitchen. Its great.

Make reservations

Definitely make a reservation for larger than 6. It will go smoother and you won't be waiting.

Walk in accepted, we made a reservation for a large group.

Walk-ins are fine, though you may have to wait depending on the timing.

Mostly walk-ins but they do take reservations. It is a good idea if it is a busy time of year
