As 7 Stars, what I do whenever I am staying at Caesars Vegas or passing through is redeem the four daily drinks for large bottles of Fiji or Evian water or Gatorade. And then I used to get 1 slice of cheese pizza at DiFara in the Caesar's food court but that place very recently closed
so nowadays I just redeem the $10. in food at Brioche or Pronto, and charge to room or pay the difference if it goes over.
In Tahoe, the 7 Stars allows redemption for just one drink at Starbucks, plus three bottled waters (they are pretty small) at any of the bars, plus $10. food at the Harvey's or Harrah's restaurants, including for a food item at Starbucks.
That just one drink at Starbucks might be the same at Caesars Vegas, but I haven't tried it to know yet.
Even while staying in house there are days when I miss out on the drink or food redemption, just don't bother with it.
