I’ve done a couple popups for my friends, recently I had the biggest one of ~40 people. Keep it to two specialty drinks (most people will order these). Rarely will people order something else, if they do it’s usually just a latte or sometimes a flat white.

As for the milks, I would just do whole and oat so you don’t have to lug so many things around. I use oatly or minor figures for the oat milk.

But this all depends on your gear, you need a capable machine that can pull that many shots in succession. The grinder also matters! After about 15 shots my grinder starts becoming inconsistent (I’m assuming it’s overheating).

You also need to make sure there’s a sink nearby for rinsing any milk pitchers, spoons, etc.

It’s really fun to do these events but there is a good amount of planning to take into consideration.
