I doubt about 8 universities....unless he counted campuses that include chep, annex, west campus, main campus, medicine, baraton, riftvalley institute, alphax, etc. They are not located within town.
Just like mj said kenyans have peculiar habits, university students have theirs too. The largest university in eldoret is moi, located about 35 kilometers from town. Its students come to town during the opening day, closing day, and twice or thrice mid the semester. Its like locating your business in CBD while relying on JKUAT, USIU and KU to keep it running.
Most University students have constrained budgets since they rely on parents for finances..bt they all need to eat, cheap/affordable food. Bt they can't keep on coming to town for lunch and supper...how about setting up cafes in the neighbourhoods of these campuses.
People around the area are constantly monied though...targeting them will surely give you good returns.
For teh students, list down 5 bizs that are demanded by university students. Start with photocopy...cafes...drinking dens...then work your way
