I live in Manhattan and tend to have a lot of visitors from all over. The first place I take them to is Gyu Kaku. It's a lovely group experience. If you go during happy hour which is typically between 4-6 if i'm not mistaken, most items are 50% off which is a steal! I recommend their fillet mignon and garlic chicken noodles, also the Chateaubriand and shrimp dumplings are delicious. This is hands down my favorite Asian (and even non-Asian) restaurant in the city!!
Also service is superb. You will get your food within minutes after placing your order.
