I know they're owned by the same people, but how do they compare with each other? We were great devotees of the old Atasca on Broadway and have never been to either the Kendall Square site or O Cantinho. Are the menus similar at the two places? We'll be entertaining out-of-town guests in a couple of weeks, and would like to come as close as possible to the charm of the "old" Atasca. . .
