So if I'm hearing you right, you have no food allergies, you just want to recreate the recipe and are hoping that someone here either works for this restaurant and is willing to fink on her employer, or is so talented a food analyst that she can taste a dish and tell you the recipe? Why didn't you just come out and say so instead of beating around the bush? You get answers that are much more on target if you ask what you really want to know.

I have friends who are chefs in restaurants (not deli's) and they all sign non disclosure contracts. But many deli's and mom and pop eating places guard their recipes for signature dishes.
