Because Tokyo is FULL of people, standing in a line is practically a sport. When a restaurant or shop is featured in a local magazine, the lines form as people want to try the cool, new thing. We saw a french fry shop in a local mag, and we ended up standing in line for an hour just for fries! I got puffy potato tots. They were sold out of falafel, the vegetarian-looking option for a fried "meat" to go with the fries.
