I like Remenisce bar and restaurant when I am out to have fun with friends they do have one man guiter shows who plays local music e.g mugithi.
Elvis makes my day with his country music attics.
Its normally fully packed if you dont like crowded places avoid it over the weekends but otherwise its great and they do have an area away from all the noise.
I also adore Nyama choma which they make to my standards! yummy
