Don Antonio's really is a one trick pony.  But it just so happens to be the Seabiscuit of one trick ponies.  There are quite a few good Mexican restaurants in L.A., but how many good restaurants have one dollar taco Wednesdays?  Only one comes to mind.

Located near Pico and Barrington, Don Antonio's is a rather large establishment that clearly makes a lot of its money selling liquor.  This works to your serious financial advantage if you only have eyes for tacos.  On Wednesday nights, people PACK this place to insane levels to get their fill of beer and tacos.  If you want to really feel special (and avoid the 1+ hour wait), come when taco night has barely begun - sometime between 5 and 6:30 pm.  You will be seated immediately, and find yourself stuffing homemade chips and salsa down your throat while feverishly mumbling to your neighbor, "are you sure we aren't cheating the system?"

They have something like six types of tacos, but the hard shell chicken and the soft shell asada are both fantastic.  Order three or four tacos, and you will be full on awesome Mexican for under $5.  Pay your ridiculously low bill and you'll be out in a flash, patting yourself on the back for having a great sit-down Mexican meal for a ridiculously low price.
