While Mug's may serve up a good cup of coffee, I highly recommend you order your cakes elsewhere.
If you are just looking for someone to copy something you saw on Pinterest (like the Mario Turtles pictured above), this is your place. But if you are looking for flavor and something your guests will actually eat, your average grocery store would be better.
My six year old loved how the mini Mario Turtles turned out and was so excited to eat them at his birthday party. That is, until he took a bite. Not one kid at the party asked for a second cupcake. Nor did many finish their first. (Keep in mind these are mini cupcakes.)
I've been directed by my child not to get his next cake from that place again. If I were you, I'd take his advice.
