The Portuguese meal schedule differs slightly from the US. Lunch (almoco) is usually the largest meal and is served between 12:30 and 2, while dinner (jantar) is served around 7:30-9:30. If appetizers are brought to your table before you order, they are often not free. Push them aside and you won’t be charged for them.
Lisbon’s streets and sidewalks can be very narrow and its drivers are bold—less than ideal conditions for pedestrians. Make sure to cross the street with care and look both ways. Make sure your presence is noticed by traffic.
The national museums in Lisbon are free on Sundays and closed on Mondays. The amazing flea markets and food markets in the Alfama’s Campo de Santa Clara are on Tuesdays and Saturdays. Bullfights take place sporadically during the summer but are usually on Thursdays and Sundays.
Generally Lisbon is considered a safe city, but it is wise to look out for pickpockets, especially on the trolleys and the metro.
