"My husband and I were in the mood for a good burger when we made a reservation at Napkin Burger. We both ordered the truffle burger. They came exactly as ordered. We were happily eating them until we both bit into somethin hard. We spit out the offending bits only to find it was bone. We each had a nasty piece of bone! We called the waitperson over who seemed dismayed and said she'd show the bones to the manager. We carefully finished our burgers. We heard nothing from the manager. We asked our server who was puzzled but went to find the manager. She reported back. She said the meat was ground fresh daily and what we had found in our burgers was gristle. Now, did he really think we couldn't tell the difference between gristle and hard bone? Moreover his answer was a non answer. When the meat is ground is not the issue. He never once came over to say sorry. We weren't asking for any accommodation. We just wanted it noted but a good manager should have come over to, at the very least, apologize. And as an aside, a friend in the restaurant business said Napkin Burger gets it's ground beef from Pat La Frieda and doesn't grind it daily themselves. This is poor management on several levels. Be careful if you eat there."
