If you're on Facebook and/or Twitter, you already have a host of restaurant tips at your disposal: Ask members of your social network what restaurants they recommend in the city you plan to visit.

Those who live in that city will be able to give you a local's perspective, and you will also hear from people who live elsewhere but have visited that city in the past.

Who knows? You might even find a dining companion or two!
