Quick Note on the graffiti, as you go into the city there is wall to wall political graffiti that is some of the best in the world. Take pleasure and delight in it.
You're basically in a full on bustling city almost as high as Cusco in the Andes. There are government buildings, an amazing plaza, well dressed indigenous Colombians (that is the distinct Colombian group here), reasonably priced food and clothes and a ton of churches next to business buildings to give workers easy access to them. Monserrat looms above with great views.
Lastly, I had my first of several meals at Crepes & Waffles, a Bogota-based, restaurant chain throughout Colombia with savory and sweet crepes (some of the best you'll ever have). The real catch is that the restaurant almost exclusively employs women - waitresses, managers, hostesses, chefs, and more for women of abuse and general working women promotion.
