Really really good. Really really expensive. Wing Lei was a second choice because girlfriend didn't want sushi from the new place at Wynn - it turned out really well.
The place is decorated unbelievably, it's worth going once just to see what the dining room looks like. Gold everywhere, and diners sit in these elaborate (read: ridiculous) thrones. Pomegranate trees sit outside a huge glass wall.
Service is great, attentive and authentic (read: Asian). The menu has a bunch of vegan and vegetarian options - not afterthoughts. We had a couple appetizers and the sea bass entree. The sea bass was easily the best dish I have had yet this year - it was outrageously delicious.
Wing Lei is very costly. A fleet of servers and bussers keep the diner service moving, and most of the dishes contain very costly cuts of meat. Wine bottles start in the $70 range.
Four stars for expensive food that is appropriately good, but not great great.
