This veggie oasis jumped right to the top of my list of veggie joints from the first day. Yes, it's an asian restaurant, so you have to immediately dismiss any factors on service. With luck, you'll get a waiter who is nice and speaks english, but really, authenticity is usually negatively correlated with customer service and english is bonus. Just bring a friend who can speak the language if it's a huge concern.
That out of the way, the 50 cent charge for water didn't phase us. I think everywhere should, and it would hopefully remind us it's not an unlimited resource. Since the portions are huge, just see it as a price for the food.
As for the food, I couldn't order enough. It's veggie, it's delicious, it's great vietnamese food (with a few pan-asian items). The best sign is I saw monks happily eating here or getting take outs and that usually makes my day. Go with a large party and share as much as you can. The birds nests seem especially popular as they were on most of the tables that I could see. I loved the soups I've had there as I'm always on a quest to get good veggie soup,(we've tried the noodle soups, wonton soup, mixed mock seafood and meats soup), and very importantly, non-herbivores are pleasantly surprised at how much they enjoy the mock meats. Yes, there are people out there who are not fans, but the beef was complimented and mentioned as a favorite. If you prefer the tofu and not-mock type of proteins, they have them here as well. Lots of vegetables, everything was delicious and fresh. Sad to see the comment below about MSG since I usually don't care for it, but if they do indeed use it, I couldn't tell so maybe it really was just a little. I'm usually crazy thirsty if it's in there. I'm a bit surprised though, since popular-with-buddhists places usually don't add enhancers like that. Hopefully that was only in a few dishes or they decided not to continue using it?
That said, get an assortment of appetizers, main dishes and if you're up to it, some of the colorful sweets at the counter to end your meal, and again, bring others with you or just order a ton to take home. The prices were very reasonable and we all had leftovers to take home. The ambiance is great, it's always packed with folks, and omni/carnivores will be fed to the brim as well. Lucky for me, my last visit had friendly staff who got by just fine in english, so don't let the gamble stop you from what will definitely be a great and satisfying meal.
Cons: sometimes pretty packed
