You have taken the first step to self employment by thinking that.Anyway,its a good idea but before you do something withmore i.e. investing,you have to do a research and a seriouse one.Also you will have to talk with the office authority to allow you to hawk food in the offices.All the best

THIS IS A BRIGHT IDEA GO AHEAD AND DO IT BEFORE SOMEONE ELSE STEALS THIS IDEA. BUT ONE THING:REMEMBER TO PUT GOD FIRST

This is a very intelligent question. Now there is a way out of every unbeaten path. This is a business that has been done before but there are still numerous avenues that haven't been exploited. this is your opportunity. How much capital do you have? very important. my advice to you is please don't try to sell in the offices because its against policy in many professional offices to sell food or eat in the office even if its lunch time. Kilimani area has very big offices with well salaried people many of them in middle class or upper middle class. these people fancy nice menus with prices ranging from 100 to 200 maximum on a wholesome and good lunch. there, you do your research, visit these food joints including the big ones before you set up your own place. please set it up near these offices and make it look decent. it will pay big, beyond your expectations.
