The setting is incredible in the evening. Croaking tropical frogs, lush greenery, impeccably dressed wait staff who are ready with a joke and never rushing you into ordering.
The selection is typical for East Africa - loads of local pale lagers which are generally rubbish, Guinness Foreign Export, and maybe a local stout.
The Food is good but pricey (as are drinks - about 3 x more expensive than a local bar down the road). You are paying for security - which is not really necessary as Kampala is quite safe- and location.
Overall - good place to meet for happy hour with colleagues - if you plan on going past round 2 change into some casual clothes and get out of the hotel for a beer and some local stew at one of the bars nearby.
