We recently installed nextable at one of my clients. Supremely impressed with the interface as well as how easy it was to set up seating charts, add servers, and manage all seating including reservations.
One of the most impressive features of nextable is the really intuitive screen. It looks absolutely fantastic on the iPad and is really simple to use with the option to set up all your servers, seating charts, and really simple drop-and-drag navigation. If your restaurant only needs a wait list, this is the solution. If you need reservations this is a great solution with no incremental fees and your customers stay with your business, not a third-party.
