I’d heard a lot about Nikkei cuisine – an unlikely sounding fusion of Latin American (Peruvian, to be specific) and Japanese – but had never had occasion to try it. Until Friday night, when I was B’s guest at Uni, a gorgeous little restaurant tucked away from the clamour of the area around Victoria station, on a quiet little street which looks more residential.

After a week at work, stepping inside almost immediately felt soothing, as we were ushered downstairs to the basement eating area, which consisted of a couple of little cavern-like nooks, and a few tables on the low-lit, polished wooden floored mezzanine level. Our tiny table was next to a set of bookshelves showcasing some vintage books and children’s toys, and the banquette was covered in a lovely, dark grey fabric. It was one of those places which immediately makes you feel cosy and settled; the waiters couldn’t have been more friendly, and nothing felt rushed.

We started with a couple of cocktails, as you do on a Friday; I went for their signature, a chilli mojito, which looked beautiful in the glass; all frosted, pale green, icy colour, with a whopping big red chilli down the side. Heeding the barman’s advice not to dislodge it, I enjoyed what was a very refreshing, not too sweet drink, which just the right hot kick as an aftertaste. B’s was a fruity confection involving sake, passion fruit and basil – also pretty good.

As B was reviewing (lucky me), we asked the maitre d’ to just bring a selection of what he felt would best showcase the menu; the head chef, Leonardo Barrio, used to work at Nobu, so I was excited to see how the food would taste.

It genuinely surpassed expectation: the consistent point is that all the fish we were served was so fresh, you could almost hear its gills flapping. We started with a trio of tacos, featuring fresh crab, and salmon and tuna tartare; all tasted of the sea, and were mind bendingly tender. Then a steamer containing one of my all time faves, gyoza: this time it was prawn, and came with a beautifully sweet/sour ponzu and chilli dipping sauce. Gyoza can often be greasy, too chewy, or dry; this was perfect, the prawn firm, the wrapper with just enough bite.

Two ceviche dishes arrived next; chunks of seabass with tiger milk, aji amarillo, choclo, red onion and sweet potato (yup, I drained the rest of the tiger milk after we’d scoffed the fish) and translucent slices of butterfish with Peruvian chilli. This was followed by a basket of tempura Tiger prawn with spicy mayo and soy dipping sauces; again, not greasy, with huge, firm pieces of prawn. Then a dish of grilled octopus, which had the most delicious, smoky flavour – attributed to the ‘Peruvian seasoning’ (it was a chipotle-ish, a bit cinnamony – whatever it was, it was addictive).

By now we were starting to feel ever so slightly stuffed, but there was more to come; a colourful plate of nigiri, featuring tuna, seabass, salmon and butterfish, and possibly our favourite thing of the night: a dragon maki, made up of 8 pieces of  prawn tempura with avocado. He had a carved cucumber for a head and wings made of frilly lettuce. We named him Bob – and then ate him.

In a nod to Barrio’s Nobu past, we then got a delicious plate of subtly flavoured miso black cod – huge, satisfying flakes, eaten with lightly grilled vegetables, including baby carrots, aubergine and peppers.

Finally, my favourite new thing: mochi – a glutinous, almost rubbery outer coating surrounding a little scoop of ice cream. B had had it before; I’d heard about it but never tried it. I can imagine anyone who’s got a thing about textures, and hates, say, mushrooms or anything ‘slippery’, probably won’t like this. I bloody loved it. We had four of the cute little squishy balls, all differently flavoured: green tea, coconut, and chocolate; absolutely delicious, and such a delicate end to the meal.

It was nice to leave knowing we’d had such good quality fish, which didn’t make us feel overfull, and I plan to come back. Prices are not too bad considering the area and the quailty; the black cod was £22.50, ceviche around £13, chef’s sushi selection £30. There were a few couples on dates, and a Japanese family, while we were in; always a good sign.

Value for money: I wasn’t paying, but I’d say around 8/10

Atmosphere: 7/10 – good buzz of chat and I think  there was some ambient music – not intrusive though

Food: 8.5/10. So fresh, tasty and good quality. A gem
