Will be "running an errand" in Pomona on 2/22. Anywhere worthwhile to eat at? Or should I just stop by SGV on my way back to WLA?
The only thing I can think of is Tijuana Tacos. I would go elsewhere on the way back unless you are feeling like tacos.
There are some decent Sinaloense places. I like Mariscos El Ostion on Holt. Good oysters, shrimp tostadas, seafood plater, cucarachas (fried shrimp), and depending on when you're there, the Micheladas are good if you're thristy.
There's a good sushi restaurant downtown -- Sakura Ichi. Or maybe head a little further out to Claremont for a burger at the Back Abbey.
