This is a small place in so called electronics district.
By subway train: Take Blue or Yellow line to Zhongxiao Xinsheng Station. Go out by Exit 1. When you come out turn right and make 180 degree turn.
Turn right at first street. You will see all the motor bikes parked on the right. Continue walking on this street.
You will cross one street and look for ComeBuy Drink Shop. After that shop, turn left. This street is busy and small.
Keep walking on the right side of the street. You will pass a Pasta Place and then Zen Zen Vegetarian Restaurant.
The gentleman with eye glasses speaks English. Ask for menu in English and ask him to fill out the order. Pay cash and food will come to you soon.
They have vege meats. Kimchi and various noodles. I like one with Sesame Paste.
The price is very reasonable. Service is good also.
Cons: Bit difficult to find
