It tasted pretty much like a yellow kiwifruit, nice and sweet and better to me than the green ones. I was disappointed however that it was still mostly green inside.
Can’t confirm what grows in front of that cathedral, but probably not, because those irises grow along lakes and rivers. (Insert comment about how many lakes and rivers in Brussels have been asphalted over making the city’s emblematic flower a rare sight.)
It tasted good, but I don’t think I would have been able to distinguish the taste from a “golden” kiwi
