I have a dairy sensitivity, hands down my favorite place to eat this past trip was Blaze Pizza in DS. They use Daiya vegan cheese, which I use regularly back home, but I've never gotten it to melt so cohesively as they do.
I'm thankful they have Tofutti and Rice Dream in the parks, but I'm seriously hoping that they start carrying Ben and Jerry's new non-dairy flavors. Leaps and bounds ahead of anything else out there.
