Wow, I wonder if you could do your reception venue up to look like a traditional Italian restaurant (assuming you're not having the reception outside too).
Then have like our local Italian restaurant does and have a live singer singing in native tongue.
I think the Greek bit would be more than well served with lots of delicious Greek food.
