The Marrakech (RAK) lounge is now dry, based on a recent visit.
My BA-issued lounge invitation stated "soft drinks and snacks" were available. There was a fridge with beer in the lounge but sure enough it was locked and the lounge attendant said it was not for BA passengers, pointing to the wording on the invitation. I have no idea who *does* get a drink.
In any case there was definitely no wine of any kind, and the only food was a couple of plates of rather forlorn plates of sandwiches. No fruit. Oh, and the wifi wasn't working, for which the attendant was somewhat apologetic. (The terminal wifi worked though.)
