What they need from you is a surface and an empty bin
Somewhere to stand glasses, somewhere for coats, and a bin that is not already full. That is the list. Front of house works the table and the hallway rather than the kitchen, which is the whole point: the kitchen is where you and your chef are, and two people cooking in a galley is already one too many.
They bring cloths, an apron and their own hands. Glassware does not arrive with front of house: ice, tumblers and bar kit come with a mixologist, and wine glasses and a decanter with a sommelier. So if you want matching glasses for fourteen, say so at booking and we will tell you honestly which of those is worth adding, or whether to borrow some.
If your table does not seat everyone, they will lay it as two sittings or as a standing course, and tell you which in advance rather than on the night.
