Opentable

Just discovered a service http://opentable.com/ for making restaurant reservations. The site claims to be free, instant and reliable. wonder if there is anything like this for Noida/Delhi/Gurgaon region. Also on similar lines, the struggle for cinema tickets makes me wish for a similar site linking all theatres in the region, with ticket availability, show timings, seat preferences and maybe even ordering popcorn in advance. Santa, are you listening? :)
