The food court in Ceasar's Palace is good for quick meals, and one of the cheaper places compared to the other extremely expensive meals, but by cheaper I mean it's like $13 or $14 instead of $40 or $50.
There is a place for wraps, a place for fish and chips, a place with horrible asian-style noodles, or sandwiches, but at least you don't have to dress up, or tip, or need to anything.
Come here to chill and relax, don't expect any food to WOW you in any sense, but come here if you're in this area of the strip and don't want to grab something quick on the the go.
