Recently, there was some discussion of the best carts in Midtown. I know that someone mentioned an excellent cart in the 40s on 6th ave (46th maybe?). I have a craving for a gyro for lunch today, and figured I could give one of those guys a try. Any suggestions/recs? I've done a search, and I know that this was discussed before, but I can't seem to find what I'm looking for. Thanks!
