Yes there is an app for that and actually has been made in New York and it's free. Its called CoolCities, you can bookmark your favorite restaurants, cafes, bars and any spot on earth you like. I use it to create my world footprint, I bookmark landmarks, museums, everywhere they have been. It has a social component as well with a news feed where you can see what others bookmark as well, you can share your bookmarks with Facebook friends, you can see where others go, you can compete with others and gain points, levels and achievements. check it out at: http://CoolCities.com https://play.google.com/store/apps/details?id=com.factoryww.coolcities
