Translation of tart in Spanish

Anyway, we left, as everybody else was leaving and once outside we understood that most people were just crossing the street in order to enter into this other night club. So did we.
After ten minutes and after drinking a bottle of water we returned to our place. It was already three in the morning. We were unhappy to miss a great party, but our physical conditions were bad.
The same night we went to a great restaurant in town (near the main street). We met a very friendly couple in their fifties from Buenos Aires. They told us many interesting stories about Argentina.
