Yes, the world that Coco and Toad lives in has Coffee and Bagels.  He probably also has an espresso machine tucked in there as well.  It’s a magic hat after all.  It’s a short hop from magic to steampunk to espresso.

You know what really annoyed me in D&D?  Bags of Holding that would rip apart if you placed sharp objects in it.  Why couldn’t they have been made with wire mesh interiors or something?  It’s not like it would’ve added much weight.
