Everything in Grand Asia is good, but not great. It may be the best in Charlotte in several categories, but it wouldn't be top 10 in the USA in any category.
The food court has good food for great prices. The box meal is a great deal. Rice and 3 choices for a good price. The duck is good along with some of the soup. Some of the buns, cakes, and desserts are very good, but some are just ok. It's definitely the best place in town for those.
The grocery store had most of what an Asian would want, but as a Filipino there are a few things I wish they had. It is the best Asian grocery store in the city.
Getting a fresh live tilapia or lobster is a very good price. You can last extra and have the restaurant cool it for you. That is a great deal to have the lobster and fish cooked. It tastes great and good for gatherings at home or eat at the restaurant with a group of 6 people.
