Our family first went Henry's kitchen 9 months ago, this place definitively delivered the most authentic Taiwanese cuisine in town upon new open. However, food quality and service deteriorates over time. And tonight was the worst experience ever. I ordered black pepper chicken as usual, service was slow :( amount was small :( taste was off :( and what really pissed me off is that, my plate was NOT prepared by a professional chef, instead it was a colleague student-like temp in charge of the entire kitchen... I will give them no more chance, period.
