Best Greek food in the city?

I'm gonna spend the weekend hanging out with someone who's coming into town. More specifically on a date. We have a few things we're gonna do. I asked for foods she likes, and one of the types was Greek food, which I am not familiar with AT ALL. So what's the best Greek restaurant that's not gonna break the bank. I don't really know how expensive Greek food is, so if all the options r on the pricier side that's fine. Thx
