The Uncle Tetsu matcha store became Uncle Tetsu Bake after a month of renovation. It just opened mid March 2017. The only item they are selling now is their signature cheese tarts. It is 3.50 for one cheese tart and 17.50 for 6.
The cheese tart tastes pretty good, but I had better in Hong Kong. Compared to Fugo desserts' cheese tarts, this one is bigger and definitely more cheesy. You have the option to eat it cold or warm up at home. It is recommended to be consumed within 12 hrs.
