Sure, the building looks vacant from the street, and it sits in a neighborhood that can get rough after, like, 10 a.m., but please look beyond this, for Jade Garden is one of the best Chinese restaurants in Dallas, a place as filling as it is good as it is cheap. And this last point is the true measure of its worth. At Jade Garden, two people can have a soup of their choice, water and an entrée for $3.50 each. Three dollars and 50 cents. That's $7 for whoever's buying. And go ahead, throw in tax and a tip. If you pay with a 10, you're still stuffing a bill in your pocket when you leave. And you're leaving full and satisfied: The food is served quickly but doesn't taste like a chain restaurant. It tastes, instead, like the steal it is.
