Dwon a couple miles from the school is a great district called Clifton - with tons of little restaurants in it. One the most affordable and also tasty and quick is a place called Shiraz. I had been there once before, but today I went again and had a much better experience.
I got a Shiraz Panini - flat bread warm with avocado and quinoa and jack cheese in it. Very very good. And some of their lentil rice: basmati rice with seasonings and lentils. This I will heat up this weekend to enjoy with some chicken or just some hummus from Whole Foods.
The people I was with enjoyed it as well. So - go, great for mediterranean food - and cheap on the wallet!
