I think the atmosphere in the downtown is different from the f.ex. Msasani and Mikocheni area. The local people rush away to/from work, and the smile isn't there as it is in the other more relaxed parts of Dar es Salaam.
In the downtown you will find public offices, postoffice, ferryboat to Zanzibar. But the embasies is located in the Msasani area.
