My experience at Uncle Tetsu's Matcha Cafe was mediocre at best.
Came in with coworkers for a beverage and saw the cold brewed iced tea on their menu. After waiting in line the cashier stated that none of the beverages on the menu are available... Why not put up a sign at the front to inform people before they line up?
I decided to try a madeleine instead. After paying I was given a receipt and waited on the side. I then noticed that you have to exchange/show your receipt to the baker to get your order. Tip for the business: The cashier really should explain this.
The matcha madeleine itself ($2.22 + tax) was tasty and had just come out of the oven. May try the other flavor (red bean) in the future.
Overall, the business needs to work on their operational execution instead of relying on long lineups to draw customers in... There won't be a lineup forever.
