Msemo (aka Southern Cross)
Shangani
This is the only real option for western food in town. It's by the sea and is a nice place to while away the afternoon. During the day it's about a 20 minute walk from the center of town, after dark it's probably better to go by taxi / tuktuk bajaji / motorbike pikipiki.
