It's so variable it's a bit hard to say, but all of them I have visited so far offers breakfast with some hot elements (can be basic but usually scrambled eggs), biscuits etc. and soft drinks + hot drinks all day, usually an afternoon tea (finger sandwiches and mini cakes - can be quite basic but can be very fancy like the IC Singapore), then evening canapes and alcoholic drinks.

SOME would offer an option to have a full breakfast at their restaurant in addition to the Club breakfast as part of the package, some have egg cooking station at breakfast time but only during some of the breakfast hours if it's extended to later in the morning, some would offer table service aspect to all of the service including the afternoon tea, some would offer premium items as part of their canape hours yet some are very basic, some would offer almost full dinner during their canape hours. Some offer a very limited selection but rather premium canape items from their restaurants, almost like tasting dishes.

Hours vary, but the evening canapes + alcoholic drinks are generally sometime between 5 pm and 9 pm.

Some are doing alcoholic drinks on free pour, some don't.
