How best to honor The King, born 75 years ago today? Fatten yourself up, of course. Today from 11:30 am on, Osso Buco near Union Square will be giving away fried peanut butter and banana sandwiches. And all weekend, Chip Shop in Park Slope will be frying cupcakes from Robicelli's—including The Elvis, a banana cake with peanut butter buttercream frosting and candied bacon, all battered and deep-fried. Bets on the higher calorie count?
