The Coyote Cafe is gone from the MGM, but Wolfgang Puck Bar & Grill is still there. Puck has other places like Trattoria Del Lupo inside Mandalay Bay.
Getting back to Roadfood Las Vegas, I would be remiss in not mentioning all the great Asian and other ethnic restaurants in Vegas Chinatown. Just a little west of the strip on Spring Mountain Road, one could easily eat at a different place every month and have no repeats. I beleive every place I have been there was owner occupied. Too many places to even name, but certainly Roadfood worthy just on the prices.
