This has been my go-to coffeeshop for over a decade now. It's one of the few places I can go and get a plain coffee that doesn't taste like regret. When they're in season, they also have the best pumpkin muffins around.
The rest of the clientele are generally polite and leave you be to your web surfing or crosswords, but there are definitely characters you'll come to recognize if you are a regular that lend the place a neighborhoody feel (such as the Bob Dylan gospel guy, who you'll sometimes find fashioning belts and other leather products across a table or two).
Added plus: for years the place had but one or two outlets, which made laptop loungers like me sad. But they have upgraded and now there are plentiful outlets! (Using one now.)
