Translation of colon in Spanish

We made a little walk into the main street of the town and were looking for a nice place to eat. This time we settled for an Indian restaurant close to the restaurant we were a night earlier.
i am student in Zurich. i think that you can learn Spanish quickly. I also registered just a month ago in order to practice some Spanish. i hope i will improve my Spanish soon at this website. We can do it together?
The counter opened 45 minutes before take-off, and we really had to beg the ground personal to check for another seat. They were friendly, but nonetheless we felt that they would do us a favor.
