Magnifico, yes and yes.

5 * hotel restaurant in New Town is advisable,it's on the way to Luo si wan

When the folks come to town or for that special occasion, there's two restaurants i usually go to, Jia Yan (嘉宴) and Wei Cai (味彩). Both are in the Green Lake area with the former set in a beautifully restored house of a former governor of Yunnan, and the latter in gardens on the edge of the lake which is great for lunch on a warm sunny day. Wei Cai also has a plush new sister restaurant on the fourth flour of the Shun Cheng building on Nan Ping Jie. Both restaurants specialise in upscale versions of the local cuisine (滇彩) but are also heavily influenced by both sichuanese & cantonese cuisines. If you go to Jia Yan go for the Qi Guo Ji (Steamed Chicken Soup), the roast chicken or the suckling pig. It's pretty easy to order in both given the picture menus.

Both are pretty expensive in relative Kunming terms, but on that special occasion, worth it.
