Whatever Tio's lacks in selection, it makes up for with a knowledgeable staff. Walk in and ask for a moderately priced champagne, and they'll direct you to the Domaine St. Michelle, on sale for seven bucks. Sure they've got all your old favorites -- Johnnie Walker, Captain Morgan, and Stoli. The wine and beer choices are decent, and there are even kegs for sale. But it's the imported hard stuff that sets Tio's apart. We're talking several types of Russian potato vodka, including a triple-distilled, wild-berry variety made by Luksusowa, plus more than 50 types of tequila, gin, and liqueur from around the world. Best of all, if you happen to be flush, plunk down cold hard cash on the counter for a ten-percent discount. Not in such a hurry to leave? Spend the afternoon watching TV with the proprietors and supping on sandwiches at the in-house deli, which stocks Boar's Head cold cuts.
