4 servers doing 26 covers in a Michelin star restaurant. In a 5-star hotel. Amazing how they keep their cool, even carrying trays of wine glasses with stems as long as the bowl's height.
Having a wine cart (literally, like a cheese cart but made for wine bottles and glasses, complete with glass rack and space for ice buckets) also makes it awesome, but what really got me was how the sommelier designed a water list as well — about 10 choices of water each for sparkling and still, listed with their mineral content.
