In LV the diamond lounges stopped offered food a few years ago. They do offer chicken wings and another hot dish 2 hours/day. [They do offer snacks for the hours they are open + free drinks.]
The Borgata Amphora lounge has always charged $10 (=10 comp dollars) admission, but their food was a level above the hot food offerings in AC casinos. At Caesars AC even though the food was free I've rarely had to wait on line, while for Borgata long lines at peak meal hours are the norm.
The big plus for Harrahs (now Ceasars Entertainment) system, is their national scope; when I look at the offers in my on-line account I have hundreds of promos some of these directly (or indirectly) will pay some (or all) of the airfare to get there
