My (24F) husband (25M) set up an ENTIRE Taco Bell dining booth in his office and is upset I want it gone

How do I even begin explaining this one...

Married for a year. Husband has always had a soft spot for Taco Bell I don't understand. I think it's pretty garbage even for a fast food chain.

Long story short, one day I come home and there's a bunch of 90s Taco Bell memorabilia in the garage. Apparently one of the local restaurants was getting a remodel and I guess he bribed the manager to let him grab a booth and some other things.

Now we have separate bank accounts so he did this all with his own money. He set it up in his office which he didn't think was a big deal because it's "his" space and I hardly go in there. He set it all up and asked me how I felt about it.

I told him my honest feelings. I thought it was ugly and tacky and glorified a less than mediocre fast food chain. Not to mention it goes against the entire motif of the rest of our living spaces. I'm still just absolutely stunned and shocked that anyone, much less my husband, would think it's a good idea to set up a Taco Bell booth IN OUR HOUSE.

Suffice it to say he's upset. I feel like I have a point because it's our house and I live here too, but he claims it's his money and he can do what he wants with it. Am I crazy or do I have a right to be upset at our house turning into a fast-food franchise?
