In addition to eating at black owned places, we did a half day walking tour of African History booked using Tripadvisor.  (Tip #6- Book your tours in advance, if possible). The tour guide was Al.  And he did an impressive tour of Lisbon, including slavery and the earthquake that destroyed the city.  Alfama was the only part of the city left standing.  According to Al, the first slaves were from Slovenia and Yugoslavia referred to as The Slavs, hence the name "slave". I have to fact check him but it sounded believable.  Also, once slavery was abolished, the Portuguese slave owners were given reparations until the 1990s.  Again.  Sounds believable.  The walk was long and meaningful.  During one of the many rain showers, we stopped in Wines of Portugal. There I learned that not only do white and red wine exist, but so does Green Wine.  Green Wine, also known as, Vinho Verde, originated in the northern region of Portugal.  The green wine was delicious and very reminiscent of white wine.  I was just happy to try something new that I had never heard of.  Al suggested we go to Pensao Amor for some evening cocktails.  Little did we know, we were being referred to sort of a sex club.  There were 10 million clues when browsing the first floor, like naked women everywhere, oversized sex toys and sexual sounds coming through the speakers by the bathrooms.  On the top floor there was a stripper pole, a mirrored ceiling, more paintings of naked women and a man painted in his underwear on the wall.  And of course, the people we met inside were extra friendly.  It went over ALL of our heads.  The next day, the tour guide to Sintra was surprised that we went to a place called Pensao Amor and translated the sex club's name.  Pensao Amor was set in a former brothel in the red light district and the name roughly translates to "pension of love".  The music decibel was low.  The music selection was terrible.  The drinks were good.  The look was sparkly and cozy.  But, after two hours, I was ready to go.  Upon attempting to leave with one person from the group, I was yelled at by the security guard to go back inside.  I was confused because when I'm ready to go, I'm ready to go!  But the serious look in his eyes when he yelled for me to go back inside a second time gave me pause.  I quickly turned around and ran up the steps.  I looked out the window and saw a mob of men picking up chairs, benches and tables walking in one direction with angry looks and on a very intent mission.  Then I saw police in riot gear.  It was about to go down outside.  Not gonna lie. I was a little scared.  I didn't see any exits and I felt a bit trapped.  I went to the top floor to warn the others that initially stayed behind. We rode it out on the top floor.  Then we all attempted to leave.  I walked out the front door first.  I got about two doors down and the same security guard yelled "go back inside!".  This time I didn't hesitate.  I ran back inside to the top floor.  My concern didn't go over well with the patrons inside though.  They told me that I was in the best place so why worry.  At the time, I didn't know we were patrons at the den of iniquity, as one of my travel friend's called it. Being locked inside a club with no exit doesn't feel like the best place to be.  Once the coast was clear, we attempted to leave a third time.  We saw police in riot gear running in one direction, so we ran in the opposite direction to a deserted street.  Called an uber. And ended the night. I still don't know why a mob formed on Pink Street.  We heard it was a soccer game the next day between Portugal and Belgium. Then we heard about turf wars.  Between the sex club with the wack music and the angry mob, I wasn't down to party on Pink Street for the rest of the trip.
