Especially if you’re going with 2 people (or 1), the set menu is the way to go. The weekday lunch set menus are fantastic deals. They’ll even let you pick 2 different ones for a table of 2.
Worst Taiwanese cuisine in Taipei. Spend your money elsewhere! The presentation is worse than that of street food, and I hate this place so much even when I didn't have to pay for my meal!
