There used to be a review here. Now there’s not. The Marathon Burger is not vegan. It’s not even vegetarian. The patty contains the house ketchup that is made with Worcestershire sauce, which contains anchovy paste. I have been informed by multiple servers that this patty was vegan. I can’t even tell you how disappointed I am to hear this, and how upset I am that after multiple inquiries I was assured that the patty was vegan. I will not be returning to Burger Up and I suggest you don’t either. A special thank you to my friend Lacey for discovering this fact after my emails to Burger Up went unanswered. If you have dined at Burger Up, like me, and have been misled, like me, I encourage you to contact them about your experience. Their information is below.

UPDATE: As of December 2012, the Marathon patty is completely vegan. The house ketchup, however, is not, so keep that in mind when thinking about dipping your fries. Thanks everyone for contacting Burger Up with your concerns. Community action, it’s super effective!
