My Dad lives in CCRC and the food is pretty good. The monthly fee (he owns his apartment but pays monthly for services and LT insurance) includes a continental breakfast and one other meal each day. For each meal, they have a printed menu and also some standard additions. They will deliver to a person's apartment if people are ill without additional cost and charge $17.50 for each guest meal.
They do have a weekly buffet on Monday, which started for those who watched Monday night football. They also have the regular restaurant meals for those who do not want the buffet. They have holiday buffets also, with everything you can think of, including wine. And luaus, Cinco de Mayo, Easter brunch etc....all with wine of champagne.
It seems that his CCRC is a more deluxe place than some others, because they have lots and lots of other benefits. So, a comparison would be a good idea if thinking about moving to one.
