My 2 cents in London

Hi! Since I'm moving to London soon I'm asking all friends who live or have lived in the city to send me any suggestions they might have of any kind (e.g. a place to go get a drink, the best sushi in town, where to go for a quick getaway, ...). I'm not looking for touristic stuff to see. Also, if you strongly agree or disagree with a spot that someone else put on the map, please comment on it explaining. Also, use the description to help me understand why that place is a must-see.
I pinned two spots already: one is close to where I'll live, the other to where I'll work.
If you want to reach out directly to me, you can write me an email: my2cents@gioaudino.com
Cheers!
