Great place, five stars instead of four because of authenticity and lunch prices. Food is pretty great, egg rolls are really delicious. When I say authentic this isn't direct from the streets of China, let's be serious you're in Arizona. But, being in Arizona and actually having dim sum deserves some acknowledgment. Lunch specials are awesome. Their food is not overloaded with sodium.
It is a clean place that is fairly 'nice', enjoyable to go in and sit down for a meal. I see a lot of comments about old people which is kind of stupid. Old people like nice, quaint places to eat and appreciate good value for their money so yeah, I'm sure they come here. You should probably follow them everywhere as they have good taste. Can't say I noticed the median age being any different than anywhere else, but then again I'm not an asshole. Anyway, check out Jade Palace and enjoy the tasty cuisine!
