I know that this is not strictly a chowhoundish question but this group certainly pays attention to where they eat so here it goes...
When I lived in New York there were a ton of places where you would grab a bowl of greens (spinach, lettuce or mixed greens) and then point to what else you wanted in it and what dressing and then the guy behind the counter would put it together, shake it up and hand it back to you. It worked very well for controlling what you ate and was a lot easier than asking for a named salad less this and that at a deli.
It seems like a pretty easy concept and there were three of them in the WFC when I worked there so it not a unique franchise. Are there any places like that down here that you all know of?
