Hi Christian87! Thank you for your question. You're partially correct. "E aí?" can definitely mean "What about there?", especially in European Portuguese. However, it also means "What's up?", and it's often used as an informal greeting in Brazilian Portuguese.
- E aí? Tudo bom? (What's up? How's it going?)
- Onde devemos colocar a mesa? Ela não cabe aqui. (Where should we place the table? It doesn't fit here.)
- E aí? Cabe? (What about there? Does it fit?)
