I spent around two days in Helsinki in mid-October. We arrived fairly late in Helsinki and after finding our hotel, we set about trying to find somewhere to eat as we had not eaten since breakfast (Finnair screwed up and were unable to provide food on the flight over). Aino was our second choice after our first choice, Sea Horse in Ullanlinna, but they were booked full when we arrived.
Feeling somewhat dejected and hungry, we decided to head back towards our hotel when we passed Aino. After looking at the menu, we decided to pop inside.
