I like Salonika's. I've been here a few times over the last couple months, and the food is consistently good.
Some of the winning dishes are the baked chicken, chicken gyros, and definitely the lemon potatoes. The salmon in pastry shell is also very good.
The staff is rushed but efficient. Given how busy they can be, they get you in and out.
Even when other lunch places are empty, you'll still find a restaurant full at Salonika's. Part of it is the prices, which are reasonable. Part of it is that the food is mostly ready to serve, so it's fast.
But overall, the quality of the food is what keeps bringing me back, anyways.
