Not sure what you can say about Lang Van that hasn't already been said! I've been here a few times with good company and always enjoyed it.
The staff is very eager to please, sometimes a little too eager...haha :). As others have stated, the menu is huge but I've never gotten anything that wasn't pretty tasty. The wraps appetizers are great, also the curry with the sweet potatoes in it is awesome. I've also tried the hot pot where you cook your own meat (steak, chicken, shrimp, calamari) and veggies in the broth...very good and fun to share!
They have also recently worked on the parking lot and there's a lot of parking around back now. Great little spot for some Vietnamese grub!
