Though several of the hotels have their own convention centers, the huge Las Vegas Convention Center is the king of the hill. It's 3.2 million square feet are housed in the North Hall, Central Hall, and South Hall, each with two levels. Annoying little speed bumps seem to be the norm in Vegas, and the ones in the Convention Center's driveways are the most unpleasantly jarring possible. There is a monorail to travel to and from the Convention Center.
From the South Hall, you can walk to Envy, the steakhouse. From the North Hall, you can walk to The Beach (http://www.yelp.com/biz/XY6qCnwb_0-XB4wevloldQ) and Piero's Italian (http://www.yelp.com/biz/anQSLdujUOp0sTCmIBi2Tg).
