The term "dishcrawl" was created by battledish.com, the first adventure game for foodies. Here for what battledish is.
A dishcrawl is an event where multiple people travel to restaurants and eat a dish in each restaurant. You can view dishcrawls at dishcrawl.com
A dishcrawl can also be considered a "progressive dinner", or a roaming dinner-literally.
We went to a dishcrawl the other night. 20 of us ate 4 dishes in 4 different restaurants!
We should go on a dishcrawl and eat at 5 restaurants tonight.
