A quick place to get some cheap Sushi. It's located in the Bus Station Terminal inside of the Taipei City Hall MRT Station on the 2nd Floor. The Sushi is cheap, and you get what you pay for, but sometimes that's all you need (and want).
Sometimes the customer service is terrible (that's an understatement). If you ask for extra wasabi or soy sauce, they will charge you 1 NT for each bag. Sometimes they won't even let you buy extra bags.
However, for something so cheap, it's really not worth it to complain. To summarize, cheap and decent Sushi, bad service, but sometimes that's what you want (and expect).
