It's been a few years, and we were only there once.
IIRC it was table service. You can sit at the counter, just like an old soda shop type counter. But you get waited on just as you would at any bar type area. (It's not an order, walk to the counter and get your food and go.)
We did not have ADRs. And we had no problem getting in there when Beaches and Cream were ridiculously packed and had slow service even to ask about getting a table.
I do not recall anything good or bad one way or another. And I wouldn't mind eating there again. Just have not had a need or desire to.
