The best restaurants serving Japanese food in Willesden Green Brent London

I visited this restaurant with three others, on the evening of 7 December. I was the only one of us who ate the sushi, and I was the only one who was violently ill for 24 hours the next day. One of the other members of the party was my wife, and we had eaten together for the 3 previous days without her getting ill, which makes me even more certain it was the sushi. Per Brent Council's on line advice, I wrote to the restaurant about this. I was not seeking compensation or redress, but in the interests of public health I wanted to let them know of the issue, especially as there is a Google Review from the previous month highlighting the same issue. I received no reply, which makes me wonder if they take this kind of issue seriously. Two episodes within 2 months is indicative of a problem. I am 61, have eaten sushi all my life in many different countries, and have never previously been ill as a result. Emptying my stomach for 24 hours was not a pleasant way to spend the day following this (not inexpensive) meal.
