Vegans: Pedantic and pretentious, or just healthy?

Chowhounders nearly came to virtual blows recently over Echo Park's tiny Elf Cafe. Although most posters seem to like the vegan, vegetarian and raw food, debate rages over whether the owners and clientele are, variously, "a little too hip," "freak folk" and "hipstery pretentious." The owners have the local band Viva K, which does not seem particularly freak folk. I haven't gotten to Elf Cafe yet -- they're only open Wednesday to Sunday evenings -- but I'll try to report back soon.
