The best restaurants serving Japanese food in Hillside Merton London

Not been for two or three years but went with high hopes as it used to be fantastic - going to show my kids how wagamama in-situ is better than the book recipes. BBQ pulled Beef hotpot was like cat food in consistency. Vegetables in my Chicken ramen were all cheaper and a bit over-cooked, the sauces had something missing - (no- mami rather than Umami ) and where the hell was the sirloin steak for chilli beef ramen - wasn't it everyone's favourite dish? Katsu curry was a bit spicy but no depth - I know everyone is cutting costs but this wasn't a good experience and my kids have asked not to go on again. Only saving grace was the service - Sohanur was chatty, fast, efficient and made the kids laugh - Not sure what the chefs were up to.......
