Fieberbrunn is normally lively and has a good selection of bars and pubs, including a high percentage of themed venues. There are several après ski spots including an ice bar right on the slopes so they're busy all day and especially once the lifts above close in the late afternoon. In the village the Riverhouse has some excellent beers and whiskies and has live music often. For Margheritas try Bar Dos Piranhas which does a range of cocktails. Other options include "Lokel Baustelle" s'Plauscherl and the Fever Fountain Saloon - themed as a Western Bar in the Alte Post.
The Tanzbar Tenne discotheque on Dorfstrasse opens at 9pm nightly until late.
