I bought this for my nieces for Christmas as a private class since they LOVE Ramen so much. They all gave it a 10/10. Her recipe was truly authentic and totally amazing… better than any restaurant we’ve been to. Chef Kumi was amazing!! She explained everything step by step and patiently waited to make sure everyone was making it correctly! Chef Kumi is very friendly and engaging! Looking forward to booking the next one!
