Wow. Easily 5 stars.
Had to look around to find this place. Directions: it's not outside in the parking lot. You need to go into the main shopping mall titled Mekong Plaza. Walk down the hall and you'll see a food court. Heng's is to the left.
I'm leaving this review because I was very impressed by the food here. I'm actually just in town, visiting from NYC. I have a favorite Michelin starred dim sum place I go to back at home, and this place can give my favorite spot a run for its money.
I got the lamb soup noodles (spicy) and the steamed soup dumplings. My girlfriend got the mapo tofu and another order of dumplings. The flavor was exquisite. And the lamb meat was actually a giant leg of lamb with the bone in. I've never seen that before in any Chinese place. Usually when you order lamb it's just a few chunks of chewy meat, but I was blown away by this guy's food.
The dude who runs this place is also really nice, polite, and incredibly humble. I left a solid tip because SHUT UP AND TAKE MY MONEY!!
