If they build it, will you come? The restaurateurs behind Bistro B in downtown Bridgeport are counting on it. Bistro B is a cozy, hip, little place with blue and white penny-tile floors, flattering lighting and high-topped banquettes. I ate some well conceived and executed dishes there last night when they invited bloggers to sample the menu. Here’s a dish I’ve never had before. Crispy artichokes over a bed of humus, with lamb’s lettuce. Loved it.
