The Cafe's and Restaurants with the best fastest wifi in Nairobi and Countrywide,your thoughts?

So i have always had this struggle where i go to a cafe like Java or CJs and ArtCaffe in some areas of the city like malls and all and the wifi has been mostly disappointing in terms of speeds so i was wondering,which are the best restaurants and cafe’s in the city and beyond (Mombasa,Kisumu,Nakuru,Malindi,Eldoret,Nyeri,Kisii and Meru) with the fastest wifi and other amenities like plenty of power outlets and comfortable seating,as well as security of the network? So far,i recommend CJs in Village Market,i got speeds of around 50Mbps there,Most Java outlets seem to be just at 5Mbps thereabout.Your thoughts guys?
