Not Your Father's Grafitti
If you merely glance at the north side of Taquerias Lupitas on Stone Avenue, you may think some really talented grafitti artist attacked the building.
However, on closer inspection, you can see this is a work of art. Its location is unfortunate because there is not easy access to it, but if you park in the lot next door at The Coffee Vein, you can walk over for a closer look.
Update (September 3, 2012): The mural is gone.
