I had lunch there on 4/2/13, the meatball sub and a bag of chips. It was fine. This is the first visit since they changed ownership and name from Brothers to Pisano's this past December. The only change is that the seating has been slightly tweeked.

They have great food and seem to be doing a good volume of business.
