For my first suggestion I would like to submit something less traditional: Tickets to G-Fest.
G-Fest is an annual convention that celebrates Godzilla and Kaiju of all kinds. It is held every year in Chicago Il.
It is held in Crowne Plaza Chicago O’Hare, and the hotel offers convention rates that are very reasonable.
Tickets to the Con are not on sale yet but last year they were somewhere around $25.00 per ticket. What you can do is make a beautiful certificate for a ticket or tickets to the con and wrap that. Then when the tickets go on sale you can order them for your Godzilla fan friend.
Of course the Godzilla fan on your list would probably like it if you went with them. G-Fest is in Chicago. You can spend your days at the convention and your evenings enjoying the sights and scenes of the city. Check and see if the Cubs are playing a home game that weekend. Be creative, have fun, enjoy Godzilla.
