London’s New Restaurant Openings

"Vegan sushi is what this new spot inside Browns in Mayfair is all about. Alex Gauthier—owner of high-end vegan restaurant Gauthier Soho—is behind it, and you can expect things like 3D-printed plant flank nigiri, miso-marinated mushrooms, and banana blossom tempura dragon rolls." - sinead cranna, rianne shlebak

My friend and I visited 123V for late lunch yesterday. It was our first visit and we were both very impressed. The restaurant is small and quiet inside, but there is outdoor seating too. We were served by 2 members of staff - both were friendly, welcoming and knowledgeable about the food served. We opted for the two hour bottomless brunch, which for £36, is great value. In that time we were brought every dish available from the menu, and had time for another 2 of our favourite plates. All the flavours were amazing and complimented each other well - my non-vegan friend said you wouldn't know the 'zalmon' was vegan. Very impressed! I would highly recommend 123V for vegan and non-vegan sushi lovers. They also serve cocktails, non-alcoholic cocktails and coffees are served with gluten free, dairy free milk for those with allergies. We'll be back again soon - and hopefully this time I'll have room for one of their desserts!

Visited for the first time on a Thursday evening with a friend. The restaurant is really cute and cosy inside and nicely decorated, although the tables are packed quite closely together. The service was really fast and friendly, the server was polite and I really liked that they brought tap water to the table! We got a mix of different small plates and the omakase sushi platter between us, wow it was delicious! The best vegan sushi I’ve ever had! Such a good range of different flavours and textures, it felt like a proper food experience to enjoy together with friends/family. Would definitely recommend!

Easily the best sushi I've ever had!!!! Everything was soo delicious. Bold flavors and rich textures, very unique, definitely different from anything I ever had. My partner and I went there today and we had the botomless sushi experience. Highly recommended. The truffle aspargus and the 2 signature dishes were my favorite, but I absolutely loved everything. The tres leches was also incredible. The service was outstanding. Both of the attendees were extremely kind and we felt very welcome!! I'll come back very soon.

Love 123V Browns! 🌱 It has a beautiful garden where you can dine, creating such a lovely and relaxing atmosphere. I went recently to celebrate my birthday, and it was such a wonderful experience. The food is absolutely delicious, and the fact that the entire menu is vegan makes it even more special. My husband and I are both vegetarian, and we were so impressed with the variety and creativity of the dishes, he loved the menu just as much as I did. The staff were attentive, friendly, and very knowledgeable, which really made the evening feel special. This was my second visit, and I’ll definitely be coming back again. Highly recommended!

I popped into 123 Browns on Friday evening after my delayed flight to London, craving some good vegan food. I went solo, no reservation, and was immediately seated at the bar. The staff were super friendly and laid-back, helping me choose a menu since I was short on time and couldn’t decide myself. I went for the Omakase menu—the chef presented me with 20 pieces of their best signature seasonal sushi, and it was absolutely incredible. Even the vegan “tuna” and “salmon” tasted authentic and delicious. The vibe was perfect—music at the right level, relaxed but lively. The menu is simple and clear, which I loved. I left with such a good feeling and can’t wait to come back with more time to explore the rest of the menu. Highly recommend this spot—it’s a great concept, and I wish more of this existed across Europe!

Gorgeous fully vegan sushi restaurant with lovely cocktails and desserts too. My partner and I got the bottomless sushi, which was amazing value for money, and tried most of the menu between us and nothing disappointed. Absolutely delicious faux meats too with vegan salmon and vegan crab. We didn't catch their name but our server was absolutely lovely and so attentive too:) Really recommend! The chef so kindly gave us a beautiful yuzu d'esser for our anniversary too, which was so thoughtful ❤️

The stellar ratings are accurate: excellent, attentive service, phenomenal taste, and great variety. We enjoyed it all, but note that the outdoor dining, while spacious, is limited to good weather. You must be sure to try it as it’s that good!

Beautiful Space and Unique Vegan Sushi at 123V Browns I had a lovely experience at 123V Browns. The atmosphere is really nice — beautifully decorated with a modern, cozy feel indoors and a charming outdoor seating area surrounded by trees. I ordered the Omakase sushi, and it was a great experience overall. The rice was a bit mushy, but the flavor combinations were creative and interesting — definitely something different for vegan sushi lovers. The staff were very attentive and kind, which made the experience even better. A great spot to visit with friends or family for a relaxed and stylish plant-based meal.
