Coffee & Chaos is a short TTRPG about running a coffee shop and dealing with small catastrophes.
The PDF is 5 pages, well organized, and packed with great art.
Supplies-wise, C&C is a little odd in that it uses cutlery. You need playing cards, but also knives, forks, spoons, and teaspoons (or proxies) to play.
The cutlery is used as stakes in checks, or as a currency to roleplay and get back some of your cutlery. The checks are basically matching cutlery type to card suit---hearts are free, but every other suit has a specific type of utensil it matches to---and the difficulty doesn't seem too high. It *is* possible you can consistently make the wrong call and whiff all of your cutlery, though.
I think this game might shine the brightest when used as a coffee shop AU for your main campaign. There isn't a lot of tension in the implied cozy setting, but if you're bringing in characters you're already familiar with, who they are as people will add some spice to the cozy.
So if you've got a long running game and you'd like to do a lighthearted sidestory, the art is lovely, the rules are fun, and the gamefeel is light and collaborative. I'd give this a look.
