Frozen yoghurt and ice cream shops show up on the map as selling beer, i.e. places with
amenity=cafe
cusine=ice_cream
I can imagine this being another localisation issue. In Norway none of the amenity=cafe sells beer, but that got solved by adding cusine=coffe_shop to all of them. I hope cusine=ice_cream will not be show in the map :)
