I have never found any tempura in Manhattan that even compares to better Tempura places i.e. Kondo, in Tokyo. In Tokyo they train for years, have the sesame oil temperature timing, and have vegetables that you don't see here. I wish there was a good tempura place in NYC
The person sitting next to me at Sushi Zen last night had tempura dish-quite huge and it looked amazing. I didn't inquire how it tasted but he sure looked like he was enjoying it. And he didn't offer me a bite!
