I actually did this way back in September and I'm glad I tried it out.
I'd say 5 stars for value, but minus 1 because I wanted to die afterwards. It was simply too much food and let me tell you, I can eat!
We went to lunch, dinner, and breakfast.
Lunch: Harrah's. 3.5 stars. Hostesses were slow and there was no one in line. WTF mate? The food was fine. Nothing stood out.
Dinner: Spice World Market. 5 stars. I loved it. So, so good. Lots of variety and it was yummy! Very fresh. I especially loved the Mediterranean section.
Breakfast: Caesar's Palace. -4 stars. Yes, negative four. Where's the food? Where is the variety? Why is every tray practically empty? Why did I waste my breakfast here? Seriously people, it's tiny. Avoid like the plague.
Do it!
