Disclosure: I was invited to dine at Roka. All opinions are my own.
I wish all Mondays could involve this absolutely exquisite feast at Roka in Canary Wharf. I think our unanimous favourite dish was the soft-as-butter black cod marinated in yuzu miso. We also loved the soft shell crab maki rolls, sashimi platter, that epic dessert boat and the best plum sake I've ever tasted.
