There are some places where you feel cooler just by walking in. Such is the case with this funky pool hall, which sets the right mood with red-felt tables, an alternative-music soundtrack and Roy Lichtenstein-esque mural on one wall. The crowd seems to consist of Cambridge’s hipper denizens who have taken time off from the art studio or recording hall to rack a few. It’s a fresh change from the meat-market pool halls downtown. The only downside: Pool tables here are a bit close for comfort—though depending on who’s at the next table, that’s not necessarily a bad thing.
