I've been to Mantras several times. The first time was close to closing time (5pm), and we were disappointed that they weren't open for dinner, and that by the end of the day, some of the items on the menu were not available. I really enjoy their chicken substitution entrees, and the juices and smoothies. It is really a large range menu that satisfies vegetarian, vegan, and raw diets.
Cons: not open for dinner, windy at outside tables, "no hay" on menu items at times
