FU is a good restaurant in the same vein as Chin Chin's, P.F. Chang's and other mainstream Chinese restaurants that's not the hole in the wall down and dirty Chinatown styled nor the cheap steamtray mall fare like Panda Express or even Pick Up Stix (which does cook to order).
The service is good here. The food, and I'm Cantonese, is good. The prices and portions of course are high and low... smaller portions for higher rates compared to Chinatown area restaurants. But keep in mind, this is in the Hard Rock. This has a different ambient vibe.
The food is authentic in that it's good food.
If you're craving Chinese food, this is a good place. If you're taking a date to Chinese food, this is a good place that's not ghetto or down and dirty dining (the type of place you'd take your girlfriend of 10+ years you're now taking for granted or your wife and kids for eats). This is a good "white folk friendly" Chinese restaurant, meaning some of the waitstaff are non-Asian and speak perfect English, any Asian women working here are not old Mama-San's nor the FOB or China Doll types, but are mainstream young Asian Americans that non-Asians can relate to, and the place is very very very clean. So, it's a really nice place to visit and has a positive and clean vibe to it.
