Lisbon's Taxi Services
There's no dearth of taxis across cities in Portugal, especially in Lisbon! The good news is they aren't prohibitively expensive - in fact, most travellers find it quite affordable. Taxis are usually coloured in black and bright green, while some are beige. All of them carry a glow sign on the roof. Fares go by the meter inside Lisbon city limits during the day, with a 20% surcharge at night (10pm-6am). Outside city limits they may charge a return fare and luggage will also bring on surcharge. It is standard to tip 10% to taxi drivers in Lisbon, Portugal.
