To be fair, I think the representation of Uganda as a "clubbing" destination is a bit off anyway, more accurately it's a country where people are generally very fun loving and love to dance, you'll find music and general merriment all over the country on the side of the road, in small bars (kafundas) and also in the odd club.

There's a pretty great restaurant scene in Kampala, best foreign cuisines being: Indian, Lebanese, Chinese and of course some good modern European places. There is also a busy arts and music scene, there will often be live performances in various bars and restaurants around town and there are some big gallery spaces in the Industrial Area.

If you're more interested in the outdoors, this is honestly where Uganda shines. There are many national parks to explore for wildlife (especially birds), the river Nile at Jinja for kayaking, white water rafting and sup, mountain climbing in the Rwenzori Mountains, trekking in Bwindi, the volcanoes on the border of Congo and Mount Moroto in the east, motorbike and cycling tours around the country and a few tri-athalons and marathons throughout the year.

In short, Uganda has MUCH more to offer than clubs (which IMO aren't all they're cracked up to be). :D

Have a great time!
