I'm not a big pizza eater but I LOVE Greek food. I found Spiros a little over priced and average food at best. I ordered the moussaka for take out which came with potato and side salad and it put me back $27. That seems steep for a dinner for one.
And the moussaka was the worst I've ever had. They do, however, make the best Greek salad ever.
If you're going for the Greek I would recommend Creatus which is down the street. Their Greek food is so much better and more than half the price.
