Not food snobs, it just isn't Jewish rye. The only spots I can think of are DZ Akins and Bristol Farms, Whole Foods or Henry's bakeroes on occasion do rye. I'll also remember to look at the famer's market next time I go.
Trader Joe's has a pretty good onion rye, my only complaint being its size and shape being rather small and round, which limits the number of slices that are really usable for sandwiches, but the flavor and texture are good..
Con Pane Bakery in Liberty Station bakes a Rye with caraway seeds on Mondays ( I believe). When I'm not in the mood for caraway but am looking for a hearty bread, I get the multi-grain instead - delish!
