Hi I have ordered from koishii several times and have always been so happy with the service and food. Today I ordered my usual salmon roll and it was revolting. The rice was crunchy and the salmon was grey and bitter I’m not sure if it was off but it has left me quite unwell. I paid with cash but would appreciate some kind of refund or voucher I’m so disappointed with this order and fear I may now have food poisoning

Thank you, we’ve just brought our order home and we've received the wrong item, crab stick cut rolls instead of tempura prawn cut rolls. We would have rather been offered an alternative if you didn’t have what we wanted as we really didn’t want crab sticks and won't be able to eat them! Can a refund be offered please? Please contact me on

Today "service" from you guys was absolutely terrible. I have ordered from you guys before and the food: 1 Always arrive on time (~30-40 mins wait time), 2 Customer support has always been great when needed an update on the order. This combined with the delight of the food being great is why I kept going back. But today both have fallen short, waited over 1 hour and 30 minutes to get 1 single sushi plater and a few coca-cola. Ring the restaurant twice to get an update, just to hear that your delivery driver is "on the way" and "will bring the food to you shortly". But it never came, even after 30 minutes between my first and second rang. Have to cancel the order, ring up the restaurant just to let them know why, and whoever answered the phone was super rude. I know customer can be a pain but swearing at one, and even over the telephone is a disgrace to the industry and absolutely dishonoured the Japanese service mentality. I have never had to witness such monstrosity from a "Japanese" restaurant before. Either clean up your act, or you may lose whatever loyalty and respect that your customer may have had for you. Such a shame and disappointment.

This evening I ordered the yakiniku bento box and I can honestly say it’s the best Bento i’ve had since returning to the Uk from Japan. In most places you tend to either get quantity or quality, I can honestly say I received both with the meal! The sirloin was tender, the taste amazing, as well as the sushi and miso soup! I’ve never left feedback for a takeaway or meal before but I had to thank you for the amazing service you provided both the meal and value for money really can’t be questioned. ごちそうさまでした!

My absolute favourite restaurant! First time I tried it I was hooked! I've probably ordered sushi more times over the last month than I've actually cooked for myself. Honestly, everything is so delicious every single time. I love this place so so much!
