I haven't seen this posted yet, but Zo will be opening a second location at 92 State Street this month.
Although they have been open for two years, the lines have been far larger this summer than I have ever seen/experienced. I frequently opt not to go the line is so ridiculous. I am happy they are successful, but I selfishly wish it was still the relatively hidden/unknown gem it was early on. (Classic CH scenario...) Thankfully, though, the quality has in no way diminished. The original gyro that I always get is exactly the same as it was when they first opened. I think they deserve a lot of credit for continuing to do things the same way, even though the increased business must tempt them to cut corners.
