You must visit the downtown, is the Bogota's heart, there you could see all kind of people, also there you'll find shoppings, night clubs, bars, brothels, discos.
Don't forget visit the historical zone, there are a lot of important museums (Gold Museum, National Museum, the Botero Donation), colonial churches, and if you like architecture, you could appreciate it.
Another interesting zone is Chapinero, is a very comercial zone, there are a lot of shoppings, and restaurants.
You would visit the north zone too, in this zone you'll find a lot of fashion stores, and is a nice zone.
And finally you must go to the stadium. The best thing in Bogotá is support Millonarios at the stadium (Nemesio Camacho 'El Campín').

Try at least to learn some Spanish or if you already know Spanish try to speak it. Don't try to speak English. First, most Colombians don't know it proper and second they are even more friendly if you're talking their language. Speaking Spanish you'll be their friend at once...
Ok. So the world over has got planetariums and most are much better than this one. One weekend we were bored and had seen most all the museums and everything, so we decided to go to the planetarium.
The entrance fee is 2,000pesos. There is a small exhibit on space and such. There is a small 'moon rock' as well as a little Colombian flag that was carried to space and back and subsequently given to Colombia, according the plaque, 'in the name peace' by the United States.
Every so often (I don't know how often exactly) they have a show in the dome, with lasers projecting on the roof the different stars and constelations and such, giving the story and history about all this. It is only in Spanish.
Carrera 7 between the highway and Calle 28. Right beside the Parque de la Independencia, Museo de Bogota and the Plaza de Toros.
I noticed there are many overhead bridges and lanes created for cyclists. I was very surprised that this city actually catered a lot of infrastructure for bicycle-travelling.
In fact, on Sundays, several major avenues are closed or halved (4 lanes reduced to 2) for people to go cycling, roller-blading, jogging or walking their dogs. There are even stages set up in the middle of the highway for peopel to do aerobics.
What a conscientious effort of the government to encourage healthy sports amongst the locals.

A great Italian restaurant: very good food (pizza & more!) & very good service. Kind of a side note but the washroom was clean, & had a cool soap dispensor. We went there twice, I had pizza both times, it was delicious.
