Restaurants come and go in London, with around half shutting within a year of opening. I fear Kanishka may well fall into this category. Maybe I was negatively prejudiced towards the venue, having never rated chef Atul Kochhhar’s previous Benares venture, but I have no specific desire to return to Kanishka. The décor felt brash, the vibe wrong, and the food not quite good enough to justify the inflated price tags.
