I had lunch at their Mercado del Rio location at Calle 24 #48-28 a short walk from the Industriales metro station.
I had their Juicy Lucy which is a hamburger stuffed with cheddar cheese, lettuce, bacon, and onion ring served in a fresh bun. It included fries and I also had a bottle of Pepsi for a total of 24,900 pesos (about $8.50). It was very juicy and tasty, so far the best burger I’ve had in Medellin.
At the time of this review (March, 2017) there were 2,900 pesos to the US Dollar.
