Update from Nairobi. TAV lounge is currently in a temporary location and a sorry affair. Small, overcrowded, no self service and one chap doing catering for the whole lounge. Poor selection of food (soggy sandwiches and chicken nuggets). The amenities listed on the oneworld lounge database are not correct, no buffet, no pre-flight dining, no rest areas and no showers. I had hoped for these and was rather disappointed by the experience.
Update: currently no drinks as they've run out of clean glasses
