I took the exact same photo of the fuck tattoos sign just a couple of weeks ago =D It's near that famous cake shop across the street you have to queue outside lol. That was a damn good cake.

In terms of souvenirs, thankfully I have no family or friends so I have no such obligations, but the wife and I do the magnet thing for our own fridge, it's a cool memory thing and I do find myself looking and briefly reminiscing half the time I go grab food.

We are careful to get more unique ones though, not just the random street, made in china ones. Some souvenir shops have some legitimately awesome stuff like the British Museum and Vatican museum.
