The massive Spec's near downtown might be the one must-see destination in Houston. While the "water wall" at the mall or the fountains by the hospitals are probably more photographed, Spec's, a liquor store, is the place everyone seems to take out-of-town guests when they visit Houston. Apart from the huge liquor selection, there's deli food, chocolate, cigars, coffee and a great beer stock. The in-store wine specialists can help you pick out a bottle that's sure to impress your friends, but even if you're not in the drinking mood, just swing by and pick up a souvenir.
