Inventive fully vegan sushi in a serene Mayfair courtyard with standout bottomless and omakase options; excellent flavors and hospitality, but expect premium pricing and occasional slow or uneven service at peak times.
Why it gets an A for overall quality
123V Browns exemplifies grade A standards through exceptional food quality that successfully reimagines vegan sushi with convincing textures and bold flavors, paired with a serene hidden courtyard setting that elevates the dining experience. Warm, knowledgeable service and strong customer loyalty reinforce its standing as a distinctive destination, though occasional peak-hour slowness and minor consistency variations in execution prevent the highest tier. The bottomless sushi format delivers compelling value for exploring the full creative range.
Restaurant Summary
Set just behind a fashion boutique, the courtyard feels calm and tucked-away, an oasis where servers walk you through playful vegan sushi. Guests rave that rolls and nigiri mimic classic textures while staying plant-based, and one diner noted, "the zalmon piece tasted surprisingly real." Service is often warm and explanatory, though peak hours can slow the rhythm. The overall scene is smart-casual and relaxed. The culinary approach leans contemporary and creative: chef-driven vegan sushi with crispy rice bites, sushi tacos, and an omakase of 20 pieces. Bottomless sushi is the value sweet spot for trying the range, while a la carte plates can feel premium for size. Most praise the bold flavors and presentation; a minority mention rice texture or sauces blending flavors too much. Families fare well here. Kids can latch onto edamame and miso, simple nigiri, and friendly desserts like Tres Leches. Reviews explicitly mention children enjoying bottomless rounds, and the calm courtyard helps. If your crew prefers traditional comfort staples, note this is creative vegan sushi first; picky eaters may prefer simpler items from the menu.
