Iranian ZAKURO & Chinese Shēnzhèn
ZAKURO is a good and unique (and low-cost!) restaurant in Nippori.

(The fruit, pomegranate [zakuro;柘榴], is native to South-West Asia.

深圳 (Shēnzhèn) , next to ZAKURO, is also an excellent restaurant. The dishes are simple but so delicious, and probably cooked in the traditional Chinese cuisine even though chefs do not seem to me to be Chinese. (And it shows a nice cost-performance, too.)
