I don't mean to alarm you, but you may be looking at the best nachos of all time.
chips, grilled marinated steak, jalapenos, black beans, tons and tons of cheese AND, yes, that's sour cream AND salsa AND fresh guacamole.
Needless to say, I ate until I couldn't move.
If you have a Mad Mex in your area(Pennsylvania & Ohio only, alas), check it out. I highly recommend it.
