The food blog Eater this week had the scoop on yet another food truck's arrival to Boston, this one called Wow Barbecue. Apparently not lacking in pride, it describes itself as serving "the only authentic BBQ lamb" in town. Look for its yellow awning on the red truck. Eater says it will serve Chinese barbecued lamb skewers, for a buck fifty each, but the menu will expand to include "grilled tofu, cabbage, eggplant, and potato skewers." Wow's Facebook page says look for it mostly on Boylston Street in Chinatown for starters or by the BU Bridge or on the campus of Northeastern.
