坐里面还是外面？

You will mostly hear this from hosts or waitstaff. However, you can use it too. If you are meeting a friend at a busy spot, just point and ask 坐里面还是外面？. It is a short, punchy question. You do not need a long sentence. Just the core words will do the trick. It is efficient and clear.

Use it the moment you walk into a place with two seating areas. It is perfect for sunny days at a cafe. Use it when you are the first one to arrive at a bar. It works great in group chats when planning a meetup. If the weather is nice, this is the most important question of the day.

Do not use this in a tiny hole-in-the-wall shop with only two stools. If there is clearly no patio, asking this makes you look a bit lost. Avoid using it in very formal banquets where seats are pre-assigned. In those cases, someone will tell you exactly where to go. Also, do not use it if it is pouring rain—unless you are being sarcastic!

In China, the choice often depends on the season and the city. In the humid south, everyone fights for the 里面 (inside) because of the air conditioning. In the north, during a crisp autumn day, 外面 (outside) is the place to be. Street food culture often defaults to 外面 on tiny plastic stools. Choosing 外面 often means a more lively, noisy, and authentic experience.

You might hear 想坐哪儿？ which means "Where do you want to sit?". Another common one is 里边还是外边？. This is just a slight regional accent change, common in Beijing. If they are very polite, they might add a 请问 at the beginning. But in the heat of a busy lunch rush, the short version is king.
