Enormous portions! I went on an empty stomach twice and both times I couldn't finish my meal.
If you're not a big eater, I recommend going with something small or even splitting one order with a friend.
Items include burgers, souvlaki, steak, and breakfast.
Expect to pay around $12-$20 per person. It is cash only but they have an ATM.
No waiter service, plenty of seating, and open 24 hours.
Just a note: I've seen security present on weekend nights. Sometimes it gets loud/rowdy with people coming in from bars/clubs.
