Spago is awesome!! Great job Wolfgang Puck! The only reason I didn't give it FIVE sparkely stars is because of the location & noise level. The location, to some, is ideal if you're perusing around the Forum Shops & want a delightful meal, but for me, it's a pain in the rear to get there unless you're already inside Caesars. And it's rather noisy since it's open to the Forum Shops.
The staff is always friendly! I always go for lunch, (sit at the bar for the fastest service). My fave is the chopped salad, all organic, fresh ingredients and the iced tea. I'm a picky tea snob and their passion flavored variety is deeeeeeeeeelish!! It's a little pricey but worth it, I always get a to-go cup, they're happy to oblige. They serve a bread basket upon seating and it's great, there's this one that has I think a cranberry in it, it's like crack. I normally end up requesting one more :)
But overall, it's a fresh, delicious restaurant that I definitely recommend. Go for lunch, you won't be disappointed.
