Here is my favourite Gelateria. It's near home, so it's handy if we decide to go and get some icecream to eat after dinner. It's the Gelateria Patagonia and it is run by the argentinians. You can see that on the wall (but also on the sides and back) there is a huge collection of argentinian plates, jerba mate's "ball" cups and all sorts of typical argentinian items.
It is a very small shop with two entrances, it's very colourful and there is alway a very happy atmosphere. Sure, they are all friendly and welcoming!
Besides, the icecream is definitely the best I know!
