NEW YORK - Besides patties, kobe hot dogs and fries, BLT Burger has a full menu of spiked milkshakes with standouts like the appropriately named Grandma's Treat (Maker's Mark, caramel, and vanilla ice cream) and The All Nighter (Kahlua, Bailey's, espresso, and coffee ice cream).
PHILADELPHIA - The Adultshakes at burger-bar PYT run the gamut from The JackRabbit Slim (vanilla or chocolate ice cream and Maker's Mark) to the mouthful that is the Peanutbutterchocolatebananana (chocolate ice cream, banana, peanut butter, and two kinds of rum).
