Be advised, Hernando's Hideaway is NOT a Mexican restaurant. It's Tex-Mex at best, so if you are looking for an authentic meal you better go somewhere else.
I went at around 10pm on a Saturday night to the Yonge/Wellesley location. My friend and I waited a good 5 minutes to be seated. The atmosphere was depressing. Dimly lit, deserted, and no music playing in the background to cheer things up. I kept waiting for a tumbleweed to pass by.
We ordered the Nachos con Carne. The busboy who brought the meal had a bad body odor. The nachos looked like they had been left out all day and tasted even worse. I think disgusting would be an appropriate word. They were probably the worst nachos I've ever had in my life.
I only had a few bites and I feel sick for a few hours afterward.
I'd avoid Hernando's at all costs.
