Now. After over a year of trying different Mexican spots all over Metro Manila and Luzon (Orale' Fort, Chihuahua Makati, Ristra's Greenhills, B&T Ortigas, Iguanas Angeles, Agave, Cantinas, Mexicali, etc.) I can honestly say there is only one place I would go to if I need something resembling Mexican food.
Hermanos Taco Shop reminds me a lot of the hole-in-the-wall joints all over California. It isn't great, but we aren't looking for the Taqueria experience I grew up with, just a good percentage of it, and Hermanos fits the bill.
Carne Asada burrito: Easily the best burrito I've had in this country. I shared the other half w/ Mia and was still pretty full. It was a little bland, but I blame Mia for asking for the salsa and sour cream on the side. I think it could use a little more herb or heat, but I generally think that about everything.
Carne Asada nachos: The good part is that there was plenty of it, and after that burrito ,finishing off this plate was a task indeed. Also they had fairly decent chips and guac. The bad news is the cheese, watered down nacho cheese and shreds of quick melt. I can accept the usage of nacho cheese over melted jack simply due to the costing of such ingredients, but quickmelt cheese should be banned from existence, I flat out hate the stuff. I probably won't order this again.
The damage wasn't too bad considering the quantity. When we go back we'll definitely get another burrito, but probably order the tacos instead. That being said its hands down the best Mexican food on the island, you can try to argue otherwise, but you will lose that argument.
