Good grief. Rubio’s doesn’t foil up their work – even upon request – but this didn’t turn out to be a dealbreaker here, since things held together OK. Still irritating, though. Construction shortcuts aside, twin scourges arrived in the form of unmelted, barely there cheese and an incongruous (and pungent!) white chipotle sauce that belonged in a silly wrap over at the other complete stooge at San Francisco’s taqueria party, 360° Gourmet. Terrible. There was no way back from these disasters, even with an acceptably flaky tortilla, palatable Spanish rice, and fair-enough pinto beans all garnering seven mustaches each. Rubio’s carnitas was overly tender (read: kind of mushy), but at least it had a bit of flavor. The mix improved the further down we slogged, which was a step in the right direction considering we didn’t even spot a bean until the sixth bite. On the whole, this tasted like the sort of oversized fast-food burrito from which Rubio's purports to stand out. It was so bad, we’re surprised it didn’t call us mean names or try to steal our MUNI pass.
