I had diner again at Umu, and it confirmed my opinion: very average. Nice setup, extensive sake list, but sushis are so so. The traditional ones are ok, but not fantastic. The modern ones are disappointing. In particular, never order fois gras sushis or aburis, they arrive cold on your dish (even if at sushi bar). Starters are fine, but nothing fantastic. Main courses vary in quality.

When I mentioned to the manager that I thought the diner tonight was so so, he asked whether it was because I had to pay the bill !! Poor guy… I have been to places in Japan where the bill was a multiple of Umu's, and the food was much better. I also have been to places in London for a fraction of Umu's, and the food was also much better. Honestly, I think Kiku next door is less posh, but a much better food quality.
