The service (from the same company as previously mentioned MyHouseHunt) works pretty much as you'd expect: enter your location and a list of available restaurants pops up, complete with when they offer service and estimates of how long delivery is likely to take. You can also make reservations if you want in-restaurant service, or browse by cuisine type.
The site currently claims to have more than 1,000 restaurants on its books, and a quick scan suggests most states have at least some coverage. Each restaurant sets its own delivery fee.
