Fort Point is now home to some lunchtime giants. I know first hand that a swooping line of hungry nine to fivers occupies Flour without end from 11-3. Their patience comes from visions of tender lamb sandwiched with spunky-sweet chutney, a palm-sized oreo cookie, and a seltzer to wash it all down. The queue at Channel Café is similarly long and proof that Fort Pointers just don’t pack lunches. Why would they? For those looking for a real power hour, though, Sportello is sit-down chic with its lunch counter style and all. It’s mod and clean, almost stark in its whiteness, but somehow the space also proves warm and charming with its friendly (and very “Boston”) servers, place mat menus and casual, up-close and personal open kitchen. Sure, there’s a “takeout” bakery in the same space, but if you have the time, the counter experience makes the meal.
