Love their cupcakes. They are exquisite and very delicious. The customer service is A Plus. Even though it’s next to the railroad, they do a great job decorating and making it a cute little store.
Aug 25 · Michael KongCute little bakery in downtown San Mateo that specializes in custom-made cupcakes. Decadent toppings, inventive coloring and designs, along with a well-trained friendly staff all contribute to a phenomenal experience. Definitely call them if you ever need to buy large amounts of cupcakes to impress your neighbors or colleagues!!
Aug 4 · Wei-Ai TaiI haven't got a chance to visit the shop by myself but my friends bought a bunch and I got to try the chocolate and the carrot ones. I love the variety of the cupcakes. Their cupcakes are moist with not overwhelming amount of frosting. I wish they could be bigger, but bigger doesn't always mean better anyway. I would love to try more flavors next time!
