I really like Modelo Negra, especially with Mexican food. Dark, sweet and perfect with fijitas or even a smothered burrito.
But the Modelo Especial, in my opinion is worse than Coors Light. So, I give it a -2 on the 0-10 scale.
I Tried Modelo Negra on a whim when HEB was out of Shiner Dark... I think I have found a new favorite beer.
