Have you been trying to get a table a Babbo since the beginning of time? Stop calling that snooty hostess incessantly a month in advance. Instead, try Rezhound, a new site that will alert you when a spot opens up on OpenTable.
Pick your region, then pick the restaurant you want to go to, the size of your party, and the time and date you want to go. Give Rezhound your email, and they'll let you know when that exclusive restaurant you've been dying to get into for months has a table for you. Magic. Delicious, ingenious magic. [h/t Twitter]
