There are as many theories on the best cup of coffee as there are caffeine junkies to dream them up. But the quality that isn't up for dispute is the "fresh-roasted" label; it's bandied about to describe everything from cans of Folgers to the beans in Starbucks' espresso concoctions. What's left unsaid in every bean-seller's claim is that roasted coffee beans rapidly lose their flavor; in a matter of days, many of the subtle tones that roasting imparts to the beans dissipate into the air. The roasting doesn't get any fresher than at Café Abir, where beans are roasted daily on the premises, and the aroma is as thick as the citywide fog. Abir is a poor java fiend's best friend; its coffee goes for $6 a pound, likely the cheapest to be had anywhere. Oh, and did we mention the 6 to 9 p.m. nightly happy hour? Two dollars a pint, which might make it the best happy hour deal in town ... but that's another story entirely.
