If you don’t know, “bleg” is blogosphere for “request for our blog readers.”
My friend told me that Super Taqueria used to sell great potato tacos. Then they stopped, and told her when she asked that it was because she was the only person who ever ordered them. So if you go, you should casually ask if they have any and act surprised and mildly disappointed if they don’t. Maybe they’ll make a comeback.
Also, if you know of somewhere else with good potato tacos, let us know.
