We raise a glass to the Fourth Story, whose excellent roster of by-the-glass wines just keeps getting better. This chic, comfortable restaurant atop the Tattered Cover boasts a cozy bar for tasting and nearly forty opportunities to try a vino you've never sampled before. The selection changes almost weekly, and it's always a well-thought-out list that includes some old favorites as well as more off-the-beaten-path choices. A half-dozen bubblies are always offered, as well as a non-alcoholic wine. The staff also endeavors to come up with interesting samplers, such as three rosés or chardonnays with something in common, so sippers can get a sense of the differences in vintage, style or vineyard. Perhaps most important, the bartenders are careful to pour 5 1/2 ounces into each oversized Schott crystal glass. Salut!
