I consider Park Central Deli somewhere I come to when I want a treat. I've been coming to this location since it was still Miracle Mile, and honestly I think they have only gotten better since they opened without the MM name. The food is always fresh and well prepared, they work diligently to keep it clean, and the staff are all very welcoming and friendly.
My favorite menu item is something you can't seem to find many other places - BBQ pastrami. The only other place that serves it is their predecessor, Miracle Mile. However, MM's is not as good. Here at PCD, the is chopped quite thoroughly and slow simmered in the sauce. At MM, I've had some really bad versions of the sandwich.
Give them a try, they will not disappoint you.
