Eat lobster in Portugal or in London?

Okay so this might be a weird question.My girlfriend and I have never had lobster in our entire lives. We are going on holiday both to London and travelling around Portugal this summer, and have decided to try it in on of those places as we live in Switzerland where lobster is costly and probably not very fresh as it is famously a landlocked country. I was now wondering if it would be better to try it in London or in Portugal? I know Portugal is amazing for fresh fish and the likes, however I don't know if this concerns lobster. And London is obviously a foodie capital so I thought maybe someone knows THE place that does lobster the right way?I'm glad for any help!!! via /r/food http://ift.tt/2tDAK9A
