When chef Kouki Watanabe took over the reins at Taihou, the Chinese restaurant his father started in 1974, it wasn't long before there were sparks flying in the kitchen.

Watanabe, 37, like most sons and daughters, had his own ideas, some formed, some only half-cooked.

"There definitely was tension, and we used to argue a lot in the beginning, especially as we were spending so much time together," Watanabe said at a recent interview in the restaurant.
