Shun Lee Palace [155 E. 55th St. (bet. Lexington and 3rd Aves.) 212-371-8844, also Shun Lee West at 43 W. 65th St. (bet. Columbus Ave. and Central Park West) 212-595-8895]
These two restaurants serve excellent Chinese food in classy settings. The prices are rather high though, so these can't be places that you visit regularly. I especially like starting with the Sizzling Rice Cake soup. Another good dish is Neptune's Net, and most of the beef dishes are delicious.
