One of the great and somewhat undiscovered things about Yangtze is supposed to be their half price sushi bar hidden in the back of the restaurant. Too bad cheap sushi almost always means crunchy, flavorless sushi, and Yangtze is no exception. It's also generally a safe bet that if a restaurant serves Thai and Chinese in addition to sushi, they probably aren't focused enough on the sushi for it to be high quality. However, if you avoid the sushi, you should be okay. Their kung pao chicken is quite good and consists entirely of chicken and not too many bell peppers, which is great for those who don't like a lot of veggies watering down their meat dish. Yangtze delivers, and often sends coupons in the mail, though they aren't worth much (something like $2 off of a $15 minimum order). Yangtze, like most places, has a $10 minimum on delivery orders. I think this is one of the better restaurants on the Promenade, though I still contend that there are no truly good restaurants there because all of these establishments can rely on lost, hungry tourists to get them by even if the food isn't top-notch.
