I love, love this restaurant. The food is just as good as Sun Sui Wah, but the service is much better. Sun Sui Wah can get really loud and obnoxious, but that doesn't happen at Imperial. The interior is gorgeous and not like a Chinese restaurant at all.
I usually order the 7-course set meal. It includes a soup of choice, two course Peking duck, crab (even if it's only two people you still get a whole crab!), prawns and chicken in black bean sauce, vegetable medley (asparagus, baby bok choy, broccoli, snap peas), fried rice or noodles, and mango pudding.
What I really enjoy about the set menus is that they serve all the food to you. They bring out the food and divide it up into equal portions for each guest. It's quite nice. If you order for three people they bring you portions for four people, which is nice.
Only once did I order off the menu. I got corn and crab soup, fresh prawns, and some other things. I don't remember the other dishes because the prawns were incredible. They were presented split in half and had been cooked with a delectable garlic sauce. I never saw the biil, but I expect they were expensive.
Overall, I make sure to visit this restaurant at least once a year. So far I have been twice this year and also went twice last year.
