Named after Mexico City’s massive seafood market, La Viga is a Redwood City favorite for oceanic fare with a Latin twist. Wedged between an industrial area and downtown, the basic but cheerful dining room draws a casual lunchtime crowd here for heaping tacos—soft white corn tortillas stuffed with fried snapper fillet, cabbage and chipotle crema; or crisp prawns with tomatillo-garlic sauce and pico de gallo.At the dinner hour, residents stream in for the famed tallarines con mariscos, a sizable mound of al dente fideos studded with pristine seafood cooked in a spicy tomato sauce. With such fresh ingredients and bold flavors, the low prices and generous portions are particularly pleasing. Don't forget to leave room for a delicate flan to finish.
