One can find many vegetarian restaurants in the San Gabriel Valley. Devout Chinese Buddhists are strict vegetarians. There are plenty of them around these parts. With thousands of years of practice, vegetarian cooks have developed an distinctly different cooking style with meat substitutes based on tofu, bean curd sheets, and soybeans substituting for meat. The bean curd sheets can actually get chewy enough to remind someone of the texture of meat. Some people swear by them.
Personally, I'm not all that impressed with meat substitutes. Don't get me wrong: many of those dishes are tasty. But they taste like tofu and bean curd sheets to me, which, I thoroughly enjoy eating. If you're a already vegetarian, it probably makes no difference. If you're an omnivore or carnivore, try ignoring the name. Face it: your dish will not taste like sliced flank steak. However, I'm sure your dish will taste very well.
Finally, just because it's a vegetarian restaurant does not mean the food is healthy. Different regions specialize in their own vegetarian dishes. Many of them are steamed, stir-fried, fried, and prepared just like other non-vegetarian dishes from that region. Deep fried tofu is certainly not on Oprah's list of healthy foods.
