I'm no expert in Spanish, but I've always thought "Chile Relleno" meant "stuffed pepper." I wish I had been warned that at Monterrey it means "pile of gravy." I ordered a lunch combo with chile relleno, and it was LITERALLY A PILE OF GRAVY. I pushed through it with my fork and found a square of bell pepper the size of my thumb at the bottom. It was not pretty, but tasted ok.
The taco that came with it was meh. Just some beef with little seasoning and one piece of iceberg lettuce put into a taco shell.
If you live in the area, and want some cheap-ish lunch as a hangover breakfast, this might be a fine place to go. If only there were biscuits to go with the chile relleno.
Our waitress was nice.
