Having grown up in this neighbourhood, I have witnessed the regression of Hanabi. When it first popped up, my brother held his birthday dinner there and the food quality and service was a solid 7.5/10 from what I recall, which is a decent score in my books. However, in the last five years the quality has drastically plummeted. The sauces taste like they came straight from the instant food packet and the ratio of protein to rice for the donburis has been disappointing. What sticks in my memory is a unagi-don that I ordered here. The dish was an unappetising artwork made of 99 percent rice and 1 percent eel marinated in a "teriyaki sauce" that tasted like honey. I would not recommend any of my friends to go here.
