One enterprising citizen came up for a use for a remnant from a giant robot the good Doctor sent against the city.
The hollowed out forearm and hand was about the size of an old rail car dinner. So that is what he did. He hollowed out the arm and tuned it into one of the trendy places to eat.

~~ he did NOT however hollow out the hand! Dr Tyche will occasionally activate it and sent it to wreck havoc in a local park.
I love the idea of a giant "Thing" from the Adams family tearing up the city. The gun will be in the index finger as the devs might object to Thing flipping off the players in order to fire. The hand can also balance on it's stump, make a fist and punch/slam/swat a super strength attack.

Not only could we get a super hero cafe with appropriate location emotes...BUT we would have one of the more unique and fun giant monsters to occasionally run around.

This would be a lot more fun that COH's giant monsters. and at certain times a Dev can take control and really have fun with "Thing!"
