The Las Vegas restaurant scene keeps evolving with Italian cuisine, gastropubs and New American fare ruling the roost of new openings in 2012. Concepts that opened last year generally stayed casual, with most of the high-end dining options remaining in the high-end resorts on the Strip. New restaurants continue to bolster Las Vegas as a great dining city, keeping up with dining outposts such as San Francisco, Chicago and New York. The best of Las Vegas can still compete with the best of other cities, sometimes even outshining other locales. Here's to hoping for an even bigger and better 2013, but in the meantime, Eater Vegas presents the 18 biggest restaurant openings in 2012.
