I know that Honeymoon sweets in Tempe did my wedding cake 5 years ago and people are STILL talking about it! I loved their service and they really went out of their way.
If you are considering going to a grocery store for it I highly recommend going to Bashas. They are the only store I know of that makes theirs fresh and doesn't just thaw out a frozen cake and slap on some frosting. They also do special orders for what you want. I know Ann at the Bashas on higley and elliot in gilbert will do anything you want. she is so sweet I have used her to make stuff for me in the past- no complaints! Good luck to you!! Hope this helps!! -S
