Bluezoo is the better restaurant, IMO...
Fulton's *can* be very good, but they are very inconsistent from one visit to the next, and on a "bad night", it can be pretty darned bad. (Cold food, small portions, indifferent waitstaff...)
Bluezoo on the other hand seems like a more "professional" place. The food is always very good, if very pricey. (The Cantonese "sticky lobster" is to die for ! ) and the service is close to flawless.
Keep in mind Bluezoo is a restaurant that routinely serves large crowds of conventioneers with deep pockets and heavy tippers, so I'm sure the competition is fierce trying to get a job as a server there...
This leads to being waited on by the 'best of the best'.
