sloan/hall If you like your greeting cards dripping with hearts, flowers and sentimentality, you'll be just fine at the drugstore. But if you want something a little more subversive, there's no better card selection than the one at sloan/hall. In a strip mall that straddles the Montrose and River Oaks, sloan/hall somehow manages to cater to both the giddy hipness of the former and the blue-blood class of the latter. While most stores overwhelm you with quantity, sloan/hall has the quality market cornered: a great series of blank cards with tasteful black-and-white images; dryly witty MikWright cards with their pasted-on photos; and selections for even the most obscure holidays. Look for boxed cards around Christmas. Rest assured, you won't accidentally send the same cards as Grandma if you get them here.
