I've been down to Black Sheep a few times since they've opened. The ambiance in the restaurant is really great, and they have really nice staff, but what is and isn't entirely vegan is a little bit harder to figure out. The staff isn't very competent on the subject. The Navajo Taco is really great, but you have to be sure to ask for vegan beans, the regular ones are cooked with meat. Also I have dreams about the prickly pear vinaigrette, probably my favorite thing on the menu. Prices are a little high, but are very reasonable for lunch.
