3.Kewpee Hotel- Olive Burger

4.Union House- Frankenmuth Style Chicken Dinner

5.Stage Deli- Double Cooked Rye Bread

7.Beltline Bar- Wet Burrito

8.National Coney Island- Hani

9.Amarando's- Detroit Botana

10.Asian Corned Beef- Corned Beef Eggroll

11.Todoroff's Original Coney Island- Coney (disputed)

Know any others?
