Where should i take my girlfriend out to eat?

I just came back from a 1 month vacation and i want to take my girlfriend out to eat in a really fancy place. im 18 and shes 17 and its our 6 month in 1 week. I wanted to take her out to eat tomorrow because thats when i get back home but the only place i could think of is olive garden. I kind of want 2 go to a romantic place though but i can't think of 1. Btw i live in clinton township Michigan.
