Taiwan is worth a trip just for the food alone – ubiquitous, affordable and mouthwatering.
For any food place that is a bit more popular and well-known in Tokyo, be prepared to stand in line. Best bet is to go at odd times in between meal times and just expect to wait for a while. Other than that, delicious food is waiting for you! Noodles are a favorite of mine, be it the more traditionally Japanese soba (buckwheat noodles) or the more Chinese inspired ramen, they are comfort in a bowl. There are lots of really good noodle places, so take your pick and enjoy.
