I want to give this restaurant 3.5 stars. I came in on a later flight last Sunday, which means = trip to Zet's before heading home (right??).
I had a burger, fries and a diet soda. The burgers are good; typical greasy spoon burger. No exciting condiments, though they do make their own BBQ sauce in house, which is better than nothing (I hate ketchup and mustard on my burger, fyi). I prefer white onions to red, but they only have red. The bun is excellent and the fries are really good. The best part of a Zet's trip is the tzatziki. It's the best I have ever had. EVER. It is creamy, refreshing and has a garlic-y bite. I dip my fries in it.
It's a bit dingy inside, it's cash only (annoying). The service is fast and friendly.
