Ah, the weekend. Perhaps you had the forethought to arrange a sitter. But if that was as far as you got, and you still don’t know where you and your love monkey are heading to, check out OpenTable online reservations. This online reservation system serves restaurants across the US and internationally; plug in your search neighborhood (e.g., Back Bay) and scope out reservation availability (and descriptions, reviews, ratings, and menus where available) for multiple restaurants at a time. No more individual phone calls!
