The American Institute of Architects reports that its survey to determine the public's favorite architecture found the Bellagio Hotel and Casino to rank number 22 of 150! The press release is at http://www.aia.org/release_020707_150Buildings
The complete list is reported in the Wall Street Journal http://online.wsj.com/public/resources/documents/info-poparch07-sort2.html
The Wall Street Journal sites allows you to sort by category, so by year, state, architect and building type. The Bellagio is the only building in Nevada to make the list -- not so surprising when you realize that only 21 buildings on the list were built 1997 or later.
