Dihua Street is not only the oldest street in Taipei, it also has a wide variety of interesting places to eat.
I went to a Japanese cake shop in the morning that sells Monaka. This is a sweet made of red bean paste sandwiched in crispy mochi wafers. Many of the other popular eateries attracted long queues, which is always a good sign, especially when you have locals queuing up.
If you're ever visiting this famous street in Taipei, now you know where to eat!
