Hahaha, yeah isn't it the way that a tourist will eat what's familiar to them instead of the good things to sample.
I looked into buying a "coffee tricycle" last summer. I didn't, primarily because I didn't want to get a loan to fund it, but I think it could be a neat thing to do on the weekends.
Ya, my wife and I tried to not eat anything that was any type of food we would eat back at home. We did good, except for breakfasts, because the places we stayed had breakfasts that we were used to eating.
That would be cool to see some stories about your adventures with your coffee tricycle. That would be a fun way to make some extra cash.
