Ever since the closing of the much-lamented cheese shop --it even had a cave! (name forgotten) where Iggie's now sits, good cheese has been hard to find in Crab Town. I have found two recently that I like, however.
Atwater's in Belvedere has a small, but very good selection with good tasting notes and the cheeses are mostly a point. Much better than the last time I was there.
The Wine Source in Hampden also has a nice selection along with a very helpful fromagelier (sp?). WS also has the real advantage of a first-rate salumi selection.
