More than 300 people attended the place to eat their burgers with fries practically for free. In most gastronomic establishments of this type, a hamburger with fries exceeds $ 2000 and sometimes even approaches $ 3000.
Some of the customers who went later to the brewery had to wait two to three hours. But the irisory price of the promotion avoided anger or annoyance, at least in the first 200 people who were served, since the offer had an established quota. "Don't miss a burger from La Birra Bar! So do not hang up and this Sunday we wait for you"
