I've been to Stone Peppers on a number of occasions and overall, the food an service have been good in the restaurant. They have a large selection of pizzas, sandwiches and salads that all have fresh, quality ingredients, and it is a relaxed atmosphere.
My review would be better overall, but the bar has never been a good experience for me. On one occasion, I went with a friend during a Penguins playoff game. It was crowded, but not excessively so. Since no tables at the bar were available and all the stools were taken, we stood near the bar and waited. It was next to impossible to get any of the bartenders to respond to order drinks. We ran into some other friends who were sitting at the bar and had requested more beers and had been waiting for 20 minutes for their drinks. I had another similar experience when the bar was not crowded; the bartenders just seem to not be interested in serving customers. In both cases it seemed like they were more interested in talking to their friends or flirting with regulars.
I'll go back for the restaurant, but never again for the bar.
