Despite being nervous and clearly out of place, the staff were incredibly kind and patient, and very knowledgeable about the food and drink options. I'm sorry that I didn't ask for their names, because everyone I interacted with was so helpful and I want their hard work to be recognised. The atmosphere of the restaurant was very calming and cosy, and allowed me to immerse myself in the deliciousness of the food and drink. The omakase was absolutely incredible, every piece delectable and very purposefully chosen with a good mixture of UK-sourced and Japan-sourced ingredients that melded perfectly together. It was an incredible experience and I will be recommending it to everyone I meet, and would love to return again someday.

FAQs

Yes, Cube Mayfair's intimate, cosy setting and several guests' anniversary and birthday visits make it a lovely choice for a special evening, especially at the counter for omakase.

Lunch is a great choice, Cube’s lunch service (Daily 12:00–15:00) is frequently described as pleasantly relaxed and ideal for the counter omakase, while dinner evenings (around 6pm and Friday nights) tend to be busier.

Smart casual is the guide, polished but relaxed, and many guests do dress up a touch for birthdays and anniversaries.

Cube Mayfair can be busiest around the start of dinner service, one reviewer noted it was very busy around 6pm on a Monday, while lunchtime is often pleasantly relaxed.

Cube Mayfair feels small, intimate and cosy, a sleek, luxury space with just a few tables and a small open kitchen that creates a focused, attentive omakase experience.

Guests describe portions at Cubé Mayfair as healthy, a few reviewers even said they ordered slightly too much after enjoying the meal.
