I may be new to costuming and setting up a cafe, but at least there are a lot of basic things to learn from this. Maybe this is my advice for beginners like me to follow:
Cafe customization and design: To me, something that is simple but appealing to consumers is one of the best things. Even so, customize it with a trendy theme so that the cafe can be more lively and also pleasing to the eye.
Cafe layout and the best way to arrange your tables and chairs: Space each table and chair so that when serving customers it is easy to pass and can also provide the best comfort to consumers when visiting to just hang out or just stop by to play with critters.
How to take and deliver orders with maximum efficiency and perform customer service minigames: For me, the most effective way is to take 3-4 orders (if it's busy) and 1-2 orders (if it's quiet) at the same time the customer wants to order so that time is not wasted and the customer does not get angry because of the delay in service.
Anything else you think players should know to make their cafe look the way they want or run it well: In terms of design and layout, at least don't pile up furniture that you think doesn't match the theme you're applying to your cafe, and don't close the distance between tables so that service is more effective.
