Lisbon, Sun, Sea and Awesome People
What an amazing city. Fish, try the fish. It's awesome and fresh and tastes amazing. There is so much nightlife here and you are so close to Sintra and the towns around the sea that you have no excuse to be bored. The people are wonderful and there are pasteis de natas (custard tarts) everywhere. Try them. The metro is so accessible and leads directly to the airport now! The views across the city are great too.
Insider Tip:There is an old fishmarket (can't remember the name sadly) which is converted into loads of wee stalls selling food with a huge seating area in the middle. You can take your food and drinks from totally different places and dip in and out of Lisbon food culture. Go here. Ask about it. Try everything.
