How expensive are the restaurants at the Nashville Zoo?

I'm going there in a couple of weeks, for Valentines Day, and I needed a reasonable answer so I know how much money to bring. Please and thank you. :) Also, the only people going are me and my boyfriend, if that helps any.How expensive are the restaurants at the Nashville Zoo?
Figure $15 apiece. Zoo restaurants are always overpriced. It's kind of like movie theatre things.\
