A hidden gem

So happy to have stumbled upon this place following a spur of the moment decision to try it after searching the area on Happy Cow. It’s like an oasis of calm in the city: shaded, beautiful, calm, green leafy outdoor area - perfect for a hot summer’s day. The vibe is bougie but relaxed. Delicious food, allergens fully labelled (and great range of options for gluten free), also has a wine list, and lovely staff. A touch on the expensive side but I feel you get what you pay for with the only other con that some of the tables are a little close together, so not great for private discussions. All in all a wonderful place and I’d love to go back to try more of the menu!

Pros: Lots of gluten free options + delicious food, Really vibey place, Lovely staff

Cons: Expensive, Tables close together so little privacy for convos

My new favourite restaurant!
The vegan sushi is incredible and you can tell so much care is put into all the different flavours and textures.
Came for unlimited sushi - the staff are so lovely and attentive, coming over frequently to see if we wanted more sushi ordered.
Couldn’t recommend enough

Pros: Flavours incredible , Great value, The loveliest staff

Cons: None at all

Nice place

We were pretty much first in through the door for opening, opted with the courtyard out the back, which is very pretty in the sunshine. We already knew what we wanted to order as we didn't have much time, so we thought we would get ordered straight away. The food still took around 40 minutes, which I thought was a little long, but it was okay. We still had enough time.
I wish I asked what the main was on the bento lunch box because I hate aubergine, I ate what I could of it, but I still really don't like it. The sushi and tofu tuce under the aubergine were both really good!
The miso soup was absolutely delicious!
As we were leaving, I wasn't sure if the waitress was joking around or felt awkward. we were leaving really quick, but we had a train to catch home.
I would come back again and try the unlimited sushi

Healthy pit-stop when shopping

**update** I've visited 123v many times in the previous venue at a Fenwick, but recently we visited 123v at the newer venue Brown's. We had the tasting menu and it was absolutely divine. Lovely staff. Lovely decor and gorgeous garden. Worth more than 5 stars. Absolutely love it!

*edit* Revisited and this time sat inside, very comfortable seating in a beautifully designed space downstairs in Fenwick. Lots of staff, and quick service. This time we ordered the burgers and the sushi platter. Food was outstanding best burger I've had in a long time! This time we felt the food we ordered was worth every penny.

Really lovely fresh tasting healthy food. Calories are listed on the menu. Blankets and outdoor heaters to keep warm. Quick service. A bit pricey for a casual bite to eat, and the cutlery was a bit clumsy, but very glad we tried it. I'd go back for the Chickpea Fries, they were really good.

Beautiful food and lovely staff❤️

Went for the all you can eat sushi and altough they were clearly understaffed, our waiters Orrin and Rian (hope I spelt the names right) made us feel like important customers and were very lovely❤️ The sushi is incredible and the restaurant itself is beautiful. We sat outside and it was warm enough with the heat lamps. We also were given the cat chopstick holders when requested that we fell in love with last time we went which was very nice. Thank you for a memorable evening 💕✨
We will definitely be back🥰

Pretty solid food

I like to visit 123V on occasion and you can't go wrong with any of the options. Good vegan options and perfect for a casual lunch.

Might have ordered the wrong thing…

Loved the crispy rice! I also got the soba noodle bowl and one of the California rolls but was less impressed. The flavours didn’t work as well together as I’d expected them to. That said, I saw other customers eating rolls that looked incredible so perhaps I got the wrong thing!

Also note that they stare on the menu that they will add a 15% service charge to all bills, but it shows up on the receipt as “optional.” Not sure exactly what that means.

The best casual vegan restaurant in London

In London you’re not short of vegan restaurants. This place is the brainchild of French chef and all round genius Alexis Gaulthier. What this man has created here is exceptional and a truly a treat of a night out. From making vegan sushi to amazing deserts I always head to this place on my trips to London. I’d eat here every day if I could.

Pros: Everything , Sushi, Music playlist

Cons: None

Incredible vegan sushi

I visited with friends and we shared the mixed platters and sushi tacos and it was a great experience. Sushi was my favourite food before going vegan so it was amazing to be able to try a huge variety of different types of sushi!

The dessert was also a highlight - the tres leches with mango sorbet was delicious!

Shoutout to Carl for his attentive service😄

Nice atmosphere

The atmosphere of this restaurant is great, I totally recommend booking a table in the back garden. The sushi is good, not at the level of beyond sushi in NYC, but so far, the best one that I had in London. I just don't recommend ordering the sushi hand rolls.

Exciting menu

I love that all the options on this menu are different to other sushi places. All the menu items were exciting and creative. The sweet potato dish with a lime and coriander sauce was one of my favourites.
It’s a pricey restaurant but the food and service are top notch.

Creative sushi from a fabulous team

What a treat, especially when the weather is nice. The garden space surrounds a big cherry tree, with plenty of cover, and it's gorgeous. I would happily spend an entire summer evening here. Even if the food wasn't good (but it is good. Very good).

Favourites were the 3d printed steak nigari and both sushi taco sets.

Service is speedy AF. If you want a quick meal, you'll get it here, but at the same time there's absolutely no feeling of being rushed.

Also noteable: waitstaff are serious professionals who demonstrate how skilled a job this really is.

Beautiful place and Beautiful food

Been there with my friends few days ago and has been amazing!
The terrace is in a very quiet place behind the shop Browns, very green with beautiful trees and plants we felt being in a fairy tale!
The food was absolutely fantastic, nice variety of vegan sushi, fresh, creative, flavourful and colourful. I don't drink alcohol and they have a nice selection of mocktails, I tried the Peach&Bergamot which was fresh and not too sweet, I really loved it!
The service impeccable, Carl is a real gem and the rest of the team very positive and kind.
To sum up, it was really pleasurable and I will surely go back to try more!

Pros: Great food, Great service, Location

Extraordinary food, unfortunate service

I cannot recommend the sushi here highly enough and wish I could've left a 5* star review. Unfortunately, the service and ambience prevented that. The staff seemed unengaged, bored, and miserable, which sadly took the wind out of the whole occasion. We all have bad days, but if you work in a public-facing job, you should greet all customers with a smile and certain energy or find another role. The service certainly didn't fit with the quality of food. Also, the atmosphere was a bit weird, I think because of the negative energy from staff, and lack of lighting. The toilets weren't filthy but definitely sub-par & needing attention, both in terms of cleaning and maintenance. I fully intend go back though, but perhaps under the influence of alcohol in order to be less sensitive to the other elements.

Pros: Best sushi I've ever had, Great location in trendy Soho, Excellent value for what you get

Cons: Staff work ethic, Lack of attention to building
