When you're travelling you tend to end up eating a mish-mash of good, mediocre, excellent and terrible food. You never know where you're going to end up eating and sometimes you can be pleasantly surprised.
On a recent trip to London I was brought to Princi for dinner.
It's, to borrow an Americanism, awesome.
The restaurant is constantly packed and won't take reservations.
The staff are all Italian and some of them probably don't speak much English.
The food is to die for.
Highly recommend it - you won't regret it!
