We've been here a few times now, and they recently renovated and re-opened. It's almost always busy, even on weekdays so best to reserve ahead of time. There are rarely caucasians here, by the dialects the vast majority of patrons are from Mainland China. I haven't been to Hunan, but the dishes are excellent, though you must like spice. Our favourite is the lamb stir-fried with green chilis, and the hot pots particularly the shrimp, huge prawns soaked in extremely spicy broth. The seaweed and pig-ear side dishes are also excellent. It is a little on the oilier side, so be warned if you're not really into Chinese. However even my husband liked it, and he really doesn't do greasy.

Service is efficient if a little brusque as we usually see at Chinese restaurants. Some servers have somewhat limited english. Parking is limited behind the building but outside of rush hour Imperial has street parking.
