I live in Bogotá at the moment and my girlfriend is from here. Most of the above is true, apart from this:
Try not to eat the arepas though they are vile
First, not eating the arepas in Colombia is like not eating the bread in France. Second, there are about 30 different types, so finding one type vile doesn’t mean they all are. Try arepas Boyacense, they are a bit sweeter than most.
Also, if you have any free time at the right moment do the Bogotá bike tour, they will take you around the must-see parts of the centre, to a tejo (explosive boules) place, to a coffee roastery and to taste fruit you’ve never heard of. The bikes are crap though 😆
