The burger at Crown Burgers has thinly-sliced grilled pastrami on a charbroiled hamburger patty. The pastrami is lean and grilled nicely. And there's lots of it as you can see in these pictures. This is a very meaty and tasty burger.
There's plenty of fry sauce (ketchup, mayo, and relish) to dip your french fries into.
I first saw Crown Burgers on Man Vs. Food with Adam Richman on The Travel Channel.
