It's always cool when a business is willing to hook up something on the house, like how airlines used to give you totally free peanuts just for purchasing a $400 non-refundable ticket! Those were the days! Doling out monthly cocktail lessons for less than nuts, Bar Adagio. Highlighted by its monthly gratis Cocktail College, the just-finished BA is a long LA-esque lounge space featuring a mix of rich wood and red leather seating, two curtains that section the room for private parties, and a pair of handmade, just-shipped-from-Spain lighting fixtures that're over 6 feet tall and look like giant Chinese finger traps, also what actually forced Yao Ming to sit out the 2009-10 season. There's signature cocktails galore (including the gin-based Lost Aviator and the vodka'd Delft Mule), all of which feature prominently in BA's semester of spirits -- a monthly orientation where behind-the-bar professors help 60 drinkers brush up on their booze knowledge (from bourbon to pisco), then take them through a hands-on pop quiz, also the plot device used in 74 percent of adult films not involving pizza delivery. Booze breeds hunger, so they've also got grub like a dippable flat bread, a selection of long-boarded pizzettas, and classic entrees like a Mac n' cheese made with garlic bread crumbs, parmesan, and aged cheddar, but not aged Cheddar Bob, since that dude just walks with a limp, and tells everyone he used to know Eminem. If the curtain partitions aren't enough privacy for you, there's a 12-person wine room in the rear with one wall that's a functional wine rack, meaning people can peek in on your party, and marvel at your breezy American Way.
