I'm half Peruvian, so I feel like I'm definitely allowed to comment on this one.
Peruvian food is fantastic, so I am more than happy that it's finally coming to London. And I have to say that the guys at Ceviche do it justice.

I've been twice already and would definitely go again.
It's a cool place and they have really put some thought into the design. There's good (Peruvian / latin) music and you can hear telenovelas on the loos. But the dining room in the back is not the nicest of spaces, so I'm always happy to just grab a seat by the bar. It's lively and fun and the pisco sours come quick!

The Pisco Sours are pretty good. Not quite like the ones my dad used to make, but definitely very drinkable.

Then it's nice to just order a few small plates to share.

The Causa is good.
Some of the ceviches are very nice.
The anticuchos (go for the one made of heart) are excellent.
Some of the other small dishes are OK.
Last time I also tried the Lomo Saltado. This one was less authentic, almost a bit deconstructed, but the beef was of excellent quality.

Peruvian food is meant to be quite spicy – aji is one of the main ingredients. The first time I went everything was lacking a bit of a kick, but they seem to raised the level of spice. So, well done boys!

Service is good and friendly, but at times struggling a bit with the huge crowds that are coming in every evening.

Value for money is OK. The dishes could be a little bit bigger. You end up ordering 2 more, but that's also because everything tastes pretty good.
