How far ahead do you need to order a cake?

I've ordered 3 cakes from them before, and each time, I placed my order about a week before needing it

Have no idea. Here's a crazy idea, why not call the store directly and ask them? Seems like you would get a more timely and accurate answer. 😉

The Mariano's in Park Ridge requires 24 hours notice.

One week before you need it..would be best...
