When the Souvlaki GR Truck first started out it didn't venture into Midtown. It stayed as far uptown as the Flatiron and Chelsea neighborhoods. I bugged them about it but they weren't ready for the Midtown masses of office workers looking for lunch. But eventually they opened up a storefront which allowed their truck to explore new areas.
But once I finally made my way to them, I knew I had to get the Greek fries ($6) which comes with feta cheese and a tzatziki sauce for dipping. Unfortunately, the fries tasted old. It tasted like they sat around pre-fried for awhile then re-fried when someone orders. I tasted the off putting old oil. It was not very tasty. The feta cheese and side dip was good though.
