Things to do with friends in the city

Hi folks of Pink City, I am from Jaipur but have been living away for ~10 years now visiting the city one or twice each year. Whenever i come back i find that the city has changed a lot. Having lived away for so long, i feel that I don't know much about the city anymore, especially things one can do with friends in the evening or on weekends (most lf my friends live away too). So i am seeking your help in understanding some of the newer, fun things that you guys enjoy doing that I should do in the next two weeks that I am in town for.
