As far as Primantis goes, this is my favorite location. The staff are all friendly and quick and I've never had a bad experience.
I usually avoid going there during "peak hours", because it gets insanely busy. During the weekends you can usually see a line of suburbanites and out-of-towners wrapping around the block waiting to get inside just to say they ate at Primantis.
Personally, I usually stop here after late summer night bike rides for some carbs and a beer. Capicola & egg is the way to go.
