The best restaurants serving Japanese food in South East

Walked into the “restaurant “ on a sunny day and the temperature inside was so cold I couldn’t believe it. I assume they don’t want people to linger? Luckily I’d taken a jacket inside with me but I was still cold. I have a few food allergens and the information on the touchscreen ordering point clearly said ask a member of staff for guidance. That resulted in being given a paper menu with a grid to show what I could or couldn’t have. I’d have preferred some personal input but he’d disappeared. Anyhow, chose a chicken dish on rice. But so did my husband and when they appeared we didn’t know which was which. Very difficult getting assistance to tell us as the only man behind the counter was flitting around like a bee. By the time we had it sorted our food was very cold. It clearly didn’t start hot but now it was quite grim. My husbands looked much more appealing than mine as his chicken had a sauce covering it. Mine looked awful and tasted worse. I don’t know how they cook it but I’d think maybe boiled? It smelt awful :/ I don’t even know why we didn’t just hand it back and ask for a refund. The rice with a bit of sauce was ok but as I said it was cold. I’ve given this establishment two stars. It would have been one except for the fact it seemed quite clean. We will never go back there as long as we live.
