SOMETIMES WE feel a little silly sipping inexpensive booze from the pricey set of cocktail glasses on which we blew more than a week's grocery budget. While everyone needs that fancy go-to set for when company's coming, we're fans of the Takeout Martini Glasses ($4.99/each, on sale) from Urban Outfitters (361 Newbury Street, Boston, 617.236.0088; 11 JFK Street, Cambridge, 617.864.0070) for everyday use. We love the way the elegant glass stems are juxtaposed against the ceramic toppers, each patterned after a super-casual paper cup. Our affinity for cheap vodka isn't quite so embarrassing anymore. @
