Portland, OR has a paleo food cart that I tried last year - the Cultured Caveman. Grass fed chili, bone broth, paleo salads, and bacon-wrapped dates. Yum.
Paris has a gluten free bakery (Helmut Newcake) and a certified gluten free restaurant - don't remember the name, but google will tell you. Not paleo, really - but a step in the right direction.
