The grandfather of fine dining in Las Vegas that is not a traditional steakhouse, I first ate at Spago during my first trip to Las Vegas as a junior in college in 2001.  I moved here in 2005 and have eaten here many times since then.  The food is very consistent, and I have not had issues with waiting too long, as the restaurant is very large.  The service is always excellent.  Wine/cocktail prices are a bit high, but you are on the strip, in Caesars, eating at a celebrity chef's place.  What do you expect?\n\nI went back last weekend and had the lamb french dip.  This was excellent, with juicy lamb, goat cheese, and grilled onions.  I highly recommend trying this.  The au jus was excellent as well, thicker than other offerings for this dish, which I prefer.  \n\nSpago is not resting on its laurels.  It still puts out very good food 20 years after it first opened.
