I like what they are doing at the M Lounge at the MIA Airport Marriott basically it is part of the restaurant and they in the morning instead of offering its own Breakfast spread, they have you walk into the restaurant and take part of the buffet and eat it in the lounge.

I cannot speak to the evening offerings as I was there on a Saturday into Sunday, but thought that allowing M Lounge guests to take part in the regular restaurant buffet was a nice thing to do.
