Its considered by many to be the best ice cream in town. On a hot summer day, which is quite rare to be honest, this might be the first place to visit for a refreshing sorbet or gelato ice cream.
If you are from a cooler climate than Iceland and the weather is unbearably hot, you might want to cool down for a bit. You might even just go there despite the weather condition if you are an absolute ice cream nutter.
Lemon sorbet, cherry Ice cream and basically everything they have to offer.
