It is free with a purchase of medium drink, but today May 15 only.
The original price is $3.49 which is not worth comparing with the McChicken or 4 pieces of McNuggets which is sold for one dollar.
The white meat quality is ok, but there is only two pickles, with no sauce, no lettuce, no tomato. I was not sure whether they forgot to put seasoning on my chicken, mine is just so tasteless. It is the worst sandwich I have ever tried on their menu.
