Why those two words together, when they are best in other pairings?
if you'd said "Cold Margarita machine", I would have believed you, and I'd assume Ken's would be quite one of the best in the business - but "Cold Fusion"? Who wants a Cold+Fusion anyway?

Option 1: Cold Margarita machine = desirable (ken's would assuredly be better)
Option 2: Jazz Fusion machine = desirable (ken's would probably be better)
