At their worst, wine lists are pompous, stratospherically overpriced, ridiculously long, awkwardly categorized and full of overexposed, yawn-inducing labels. But at Caveau Wine Bar, the 75-bottle list (55 are available by the glass) is an easy-to-navigate document of new discoveries, small producers and familiar but not overrated labels. The polished yet easygoing staff is well-versed in wine education and just as enthusiastic about pushing a $30 bottle of vino as a three-digit one, which is a welcome change to the rigorous sport of upselling. Those prowling for deals know to show up at 4 p.m. for the daily happy hour, when pours priced at $12 and over are knocked down to five bucks and glasses over $13 are sold for half off.
