We've had a very warm and good time here. My sister is a big fan of Japanese food and she really enjoyed the fish udon and beef rice. I love the plum wine and fried tempura. Staff are friendly and quick service. Recommended ✨🥂🫶🏻

Had a very pleasant dinner at Koys city, but I think it's a bit expensive. We ordered one starter, two mains, one dessert and spent £60 in total.

All the dishes were good but I think the price for the starters and dessert were too high for what they were.
The udon portions were really good, and the dishes were flavourful.
Service was great.

I might go back for a bowl of udon but it hink value for money is not the best.

This place made me fall in love with udon. The noodles are so bouncy and addictive! Zaru udon is my go-to because it really lets you enjoy that perfect texture, but their small plates (especially the pork belly) are also fantastic, and I sometimes try the seasonal menu too. The only downside is it’s a bit pricey for what it is. I much prefer the City branch over Soho—it’s less crowded, and you can reserve a table!

Koya City: Best Udon in London’s Bloomberg Arcade

Koya City, located in London's Bloomberg Arcade, is the second noodle bar from the Koya brand, which first opened in Soho in 2010. Launched in 2017, Koya City expanded its offerings to include a wider range of udon preparations and izakaya-style small plates, catering to a broader audience seeking authentic Japanese cuisine in the heart of the city.

History of Koya City in London City Districts Blooming with Udon Excellence 

Nestled in the heart of the City of London at 10-12 Bloomberg Arcade, Koya City stands as a celebrated beacon for enthusiasts of authentic Japanese cuisine, particularly udon noodles. As a vibrant continuation of the renowned Koya brand, it carries forward a rich history dating back to its origins in central London.

The Soho venue became a culinary landmark, attracting foodies and cultural explorers alike, captivated by the rich flavors and fresh ingredients that defined Koya's offerings.

Expansion and relocation to Bloomberg Arcade

In 2018, Koya expanded its footprint by opening Koya City in the historic Bloomberg Arcade in the City of London.

The original Soho site has since closed, but the City branch continues to carry the mantle of authentic udon excellence.

Adapting through challenges and evolving tastes

The COVID-19 pandemic in 2020 presented unprecedented challenges for the hospitality sector worldwide.
