My boyfriend and I are in the restaurant industry and are very interested in checking out as many restaurants as possible during our 3 night stay in Vegas next week. What we would like to do is pop in unreserved and sit at the bar for a couple appetizers and drinks. We will be in town for Sun- Wed next week and were hoping to check out L'Atelier, Mix, Tao, Bouchon, Olives, DB Brasserie, Spago and Nobhill. Do you think this style of dining will be possible for us in Vegas? Any other recommendations? We are at the Signature at MGM but happy to dine anywhere around the Strip.
