Like you a week before we were still without any plan. But we ended up doing something quite and peaceful with 4 friends and it ended around 6 o'clock!
Each couple was supposed to bring some little stuff to eat more like starters... And, well, we didn't really realize we had only to bring a third of what everybody would eat..
And three couples got together that night with food for like around 18 people
Enjoy! We were full and didn't stop to eat en entire night. It was amazing and so fun.
