One of the most promising groups at Startup Weekend was Curb Serv. Their project is (going to be) an app that allows any restaurant to have delivery to cars. With their app, people can order food from their favorite restaurant, and have that food delivered to their car. Wouldn't that be nice when it's raining or snowing? Curb Serv is all about enabling that convenience and they do it with a great, sassy attitude. The app is in beta right now, so you can sign up to become a beta user at their website.
