Nevertheless, I exchanged conversation with one staff at the store and told her what I needed. 20 cupcakes for kids in regular size since they also have mini and jumbo size. Then, I waited for 5 minutes and my order was ready. They sealed the boxes so I couldn’t take a peek inside (I was afraid I would spoil the cupcakes), but I got positive feedbacks f

We’ve been buying from sibbys for years, they’ve got amazing quality cupcakes, and we’ve even cater with them before. They are cupcakes are moist and the frosting is great, I love the decorations. Just picking up your desserts. The atmosphere is great. It seems like all the workers are friends with each other and laughing just overall a great place to support
