Ah, the galley is that cabinet at the end of the room. It will have some more detail when I get to it. There will also be some more storage indicated, for items needed immediately...salt, spices, ale, water, etc. Bulk stuff will be kept in the hold.

The WotC map I looked at had a whole kitchen. I reckon that's too much...there's a reason small American apartments have a thing called a "galley kitchen". So, food is cooked and eaten in the fairly small galley/mess. I should change the label I guess.
