On their menu it says add "cheese 50.00" that has to be a typo?

Hi Autumn! Where do you see that? It says .50 when I look. Thanks! (PS..Def not 50 dollars!)

I can't say for sure, but I've been there a fair amount of times and have never once paid fifty bucks for cheese.

Of course it's a typo error

I would definitely say so..
