Can you make a reservation or is it first come first serve?

You can definitely make a reservation, but most times, the wait is minimal.

I would make one if you are eatting on a Friday or Saturday night. I have waited more than an hour on several occasions.

Yes, reservations are welcome

Yes

It's busier come dinner time over the weekends, so a reservation might be a good idea. Other days, you likely won't need one.

You can but not necessarily.
