Here's its first logo draft, btw.
And the new addition, Kenzie Cafe. A new fictional location replacing Macker Cafe, due to misuse of the name, and unofficial association with Gus Macker (the name that Mack was unintentionally derived from)
The 'Kenzie' name comes from the rebranded character, McKenzie Riverson. Who had previously joined the roster since 2 months ago, prior to the File Loss incident (original image not found).

What is known about the menu on KC is starbucks-like ingredients but likely better. And free cakepops, yes.
