I've gone to Great Wall for years. But the best thing that impressed me lately? Going there for Dim Sum at 12PM on a Sunday with a party of 8. We were seated INSTANTLY despite the huge line outside. Why? My family has serious connections! It's like the Asian mafia of food.
The Dim Sum dishes are good. Not too greasy. Baked Egg Custard Buns make me drool. Everything else is great too. They have a huge selection served in carts.
The dinner menu is very good too. Live seafood. Lots of servings. Family style.
If you come here, be sure to bring a big group. You will leave full and happy! As for the pricing, I can't comment on that. My Asian Mafioso mom usually fronts the bill.
