One reviewer called Airport Gate a poor man's Zet's. Not bad, except that suggests the prices at Airport Gate are low and they're not. Average to slightly high is more accurate. But the food, sadly, doesn't compare. I order gyros on a pita. The gyros was okay but the tzatziki was weak and watery. The entire sandwich tasted like a collection of its ingredients rather than a whole thing in delicious harmony like you'd get a Zet's.
My brother ordered the chicken shawarma salad - a dish not available at Zet's. He said it was tasty enough but it was apparent that the chicken was very thinly slices, too thin, and there wasn't much of it.
While there was hardly anyone in the restaurant, it was difficult to find a table that didn't need a wipe. On the plus side, they take credit card, unlike Zet's. Overall, there's no need to come here when Zet's is just a few minutes away and the food and value is FAR better.
