There weren´t that many people there. Something I have noticed in Greece for instance as well. In many Mediterranian countries lunch is kind of sacred and isn´t anything they think of lightly. Lunch can be a 2-3 hours business and is normally the largest meal of the day. In Spain and Portugal you can get a 3-course meal with wine and coffee for 8-10 euros. In Greece fast food chains have tried to establish many times but when you have your own fast food in form of pita gyros (meat, tomatoes, onions in a pita bread with tzatziki and chips) for about 2 euros why go to some other American fast food chain?
But if to return to Mc donald´s this specific lunch in Portugal. I ordered a hamburger, a salad and mineral water. I was very surprised when I got a small bottle of extra virgin olive oli for my salad.Even the Mc Donald´s restaurant met its customers´demand and provided them with high quality salad oil. No mysterious dressings here.
