I eat at Buddha's about once every 3 weeks; whenever I feel like indulging in some greasy, satisfying Chinese food.
They have really delicious veggie ginger beef, mock fish dishes (my new fave), Singapore style vermicelli noodles, etc. They have a "meat" menu and a "veggie" menu so be sure you have the right one! Some of the dishes on the veg menu are NOT vegan-friendly (like the chow mein) so be sure to ask.
It's a westernized food, so there are lots of deep-fried stuff drenched in sweet/greasy sauces.
Service is really typical of a Chinese restaurant, I feel. Blunt. Not exactly graceful. Some may construe as rude. But there is that cultural difference. Don't expect your waitress to be super-attentive or personable. All this aside, the service is generally accurate and fast.
Prices are expensive for what you get (comparing to similar restaurants in Vancouver) but don't have much of a choice if that's the kind of food you want in Calgary.
All in all, I would recommend this restaurant to friends. It's tasty and good for a once-in-a-while indulgence.
