That reminds me of the infamous Halal Guy's gyro cart located at 53rd and 6th in Manhattan. The food is sub-par at best but there is always a line of 30+ (I've seen nearly 100 before) people who, at least I think, are there for the experience more than anything.

There are literally dozens of other gyro carts scattered about the vicinity, some with much better food, yet that cart consistently has a huge line.
