Disclosure, we made this app. But we made it because it didn't exist. When we travel, we like to eat at local places, not chain restaurants. And my wife really likes the Diners, Drive-Ins and Dives TV show which has been to a lot of places around the country (900+ after 29 seasons), so most places we go, there is a DDD nearby.
So every time we travel, this is the first app we typically open after we land. And then we figure out where we want to eat for the next couple of days from it. If there aren't a lot of options, then we turn to Foursquare.
