Do we need to make reservations for tonight?

Not sure the size of your party but they don't take reservations for small parties (e.g 2 people)

You can personally I never have and usually do not have to wait.

Depending on your amount of people, because it does get crowded the later in the evening you go

I went with 7, and did not make reservations. Be prepared for a wait to be seated on weekend evenings.also they have valet parking to manage cars in the relative small parking lot. Great food by the way. I had the clam bake, and left stuffed.
