Zagat Survey has released the results of its Las Vegas Restaurants Survey, with detailed local data, ratings and reviews available on zagat.com. The Survey includes a total of 523 Las Vegas restaurants based on the opinions of 3,736 local reviewers.

This year, the eponymous Joel Robuchon at the MGM GRand Hotel and Casino has been awarded Top Food and Service by Zagat reviewers, boasting a "bucket-list dining experience." The "extraordinary setting" of the Bellagio's Picasso has helped the restaurant earn Top Decor honors again this year, while Thomas Keller's Bouchon at the Venetian Resort and Casino was named Most Popular.

The guide rated Mastro's Ocean Club, located in Crystals at CityCenter as this year's top-rated newcomer thanks to its "exceptional" and "unique dining experience". The Cosmopolitan of Las Vegas also provided 10 of this year's 30 newcomers. Among those restaurants are Comme Ça (David Myers), Blue Ribbon Sushi (Bruce and Eric Bromberg), Milos, Estiatorio (Costas Spiliadis) and STK (Top Chef's Stephen Hopcraft).

According to Zagat Guide, the prize of an average meal in Las Vegas actually increased from $44.44 in the last Survey to $47.53 this year. The increase maintains the city's distinction as the nation's most expensive dining locale, topping cities like New York ($41.76) and Miami ($39.86), which are both well above the national average ($35.44). When it comes to tipping, local diners leave an average 19.4% tip, which is greater than other in Western cities like Los Angeles (18.7%) and Seattle (18.6%).

The survey shows Las Vegas diners are eating out less. In the past five years, the average number of meals out per week has declined from 3.8 in 2005, to 3.3 in 2010, only slightly above the national average of 3.1. Furthermore, 15% of the reviewers said they are eating out less now than six months ago.

"The increase in meal cost this year is not surprising; as with all things in Las Vegas, dining out is a form of entertainment. Many of this year's most exciting newcomers are in hotels – and major hoteliers understand that in order to be a contender on the strip – they must have first-class restaurants." says Tim Zagat, CEO of Zagat Survey.

The guide also shows that food trucks are becoming a popular option in Las Vegas, offering mobile and affordable fare to foodies up and down the Las Vegas Strip. A notable 20% of reviewers actively follow food trucks and other restaurants via social networking sites. Two popular trucks include Slidin' Thru, serving up gourmet Angus and pulled-pork sliders and Patty Wagon, the mobile offshoot of the Red Rock Resort's LBS.
