Do we need reservations?

I am fairly sure they don't allow for reservations

No. But it is popular, so either go early or later

We have always just stopped in to eat. We have never had to wait. We have ate outside must of the time.

You should have no reservations about eating at Sammy T's

You do not need a reservation. It was busy the other day so We sat at the bar. I have to say even if you have to wait, it's worth it!
