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

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!

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.

Visited today for our first ever bottomless sushi, and as a non vegan I’ve got to say the food quality was very impressive! The salmon and tuna sushi you can see in the picture are EXACTLY like their meaty counterpart in both taste and texture, it’s amazing. The deep fried rice was delicious, and honestly as you can see all dishes are really well presented. I’d highly recommend the place to anyone visiting London as long as they’re not on a budget, the bottomless sushi with 2 beers, a tea and a cake cost £110. Also worth mentioning 15% discretionary charge automatically on the bill which I hate. Also, the chairs are the worst chairs I’ve ever sat in. If you’re a larger person you literally won’t fit in them, truly awful.

Amazingly great place and great food. Loved it all! Perfect environment with patio where it was laid back! Amazing wine as well. This was my most favourite Gauthier spot!

Food was delicious, service was great and the ambience was fantastic. We had 2 of the omakase (chef's choice) sushi platters. 40 pieces of a wonderful selection of California rolls, nigiri and sushi tacos. 40 between 2 is very, very filling though!. Would highly recommend if you're in town and want some lovely sushi!

Flavourful, beautiful, and delightful! Much better than non-vegan sushi for health, safety, and environment. The food tasted even better thanks to the very pleasant staff Orrin. Thank you guys. 💚

This spot is amazing for vegan sushi! We were blown away by the menu—there were so many incredible options that we couldn’t decide what to order. Luckily, they offer an unlimited sushi option, so we went for it and got to try everything on the sushi menu. Best decision ever. The menu is creative, packed with bold flavors, and beautifully presented. The staff were incredibly friendly and took the time to explain each dish, which made the experience even better. I also asked about the rice preparation, and I was really impressed with their attention to food safety and quality standards. They carefully control the temperature, acidity, and texture to ensure it meets the highest standards, which really shows in the final product. They also offer a tasting menu, which is another great option. We’ll definitely be back. Highly recommend!
