The biggest challenge when you lunch at Salumi is not standing in line. (Suck it up and be patient, and you will waddle out of there with a full belly.) No, the biggest challenge is figuring out what to order. But if it's listed among the specials, go for the Marco Polo, especially if you don't mind breaking a sweat. This flavor explosion is built on wasabi-marinated chicken. Prosciutto is piled on, followed by caramelized onions, Mama Lil's hot peppers, and more wasabi. Hot damn! —Leslie Kelly 309 Third Ave. S., 223-0817
