...doesnt need to cost $30 unlike a steak or a lobster for example.!
Well considering the chef, it really wouldn't surprise me if these burgers are from several cuts of prime meat i.e. cuts of steak...thus making it a higher end burger vs your greasy burger from somewhere else. (Not that I don't love a good old fashioned greasy burger mind you.) Go to just about any good butcher and look for "Prime" beef and you pay a decent penny for it.
