not bad.. rigoberto's is in an old dairy queen building on hwy 99 in west albany. there's a small dining areainsidebut it's set up mostly as a drive through place. the restroom is precariously positioned outside and access requires walking through the drive-thru vehicle lane. (the bulb in there takes a while to illuminate, so be patient, or rely on mussel memory for accuracy. your call.)
i had their fish taco plate ($7) that came with beans and rice. carol had one carne asada and one lengua taco. ($2.49 ea.) they have a well stocked condiment bar; radishes, cilantro, pickled carrots, roasted chilies, cucumbers, lime wedges and salsas to satisfy any taste.
carol liked both her tacos, but thought the lengua (beef tongue) was especially good. my fish tacos were loaded and very good. all tacos were double wrapped with big 6" hot corn tortillas.
it's pretty good, pretty authentic mexican food for cheap!
