The Buckhead shopping district is really separate from the Buckhead villiage nightlife area. Lenox and Phipps Malls are still tops. There are still some excellent restauarants in both Buckheads but the nightlife has gone down hill.
BTW, there is a third "buckhead" which is the old money mansion district. All three neighborhoods are adjacent and locals refer to them simply as Buckhead. The shopping discrict is also an office district.
