1300 Lisboa, Portugal | Doca de Santo Amaro de Alcântara - Gate 3 - THIS IS THE ADRESS TO THE UBERS OR TAXI
This dock is the close to the bridge. So, inland and looking to the river, gate 3 is set at the left (east). Is the opposite side of the brigde.
In doubt, look for the restaurant " Rui dos Pregos". It is the closest gate to this restaurant.
