Tasty, low (or no) MSG in most dishes, clean (food, waiters, restaurant overall). What else can you ask for?
Keep in mind that this is not your typical Chinese food restaurant. Food doesn't have as much MSG, and thus the taste is not as intense, but it's healthier as a result. Other than the intensity of the taste, food is tasty and feels like it has quality ingredients.
Place looks and feels upscale (if somewhat dated), even though prices are quite reasonable and most clientele is dressed casually.
