Kevin Freeman and Geoff Peters of GK Media are pretty cool guys. They launched www.foodvancouver.com in April 2005. Part of the mandate of the site is to help those with special dietary needs find restaurants accommodating of those needs.
Today the site just got better. Kevin and Geoff added a downloadable restaurant guide for iPods.
I checked it out and it’s pretty easy to download and install. Any iPod newer than the 2002 model supports the guide. You load the app into the Notes features of the iPod and then off you go.
