Brian Freedman says Opa is one more reason to head to the 13th Street corridor, the pikelia platter setting the tone right from the start.

[W]hat you get at Opa is a trio of dips that rise above the vaguely depressing status quo: The hummus burnishes a darker shade of tan from the hefty addition of smoked paprika; the tzatzaki is mouth-watering, healthy-tasting; the tirokafteri soft and sensual, the feta base exploding with the bright heat and vivid color of red Italian frying peppers.This is as successful and as understated an opening salvo as any Greek restaurant’s in the city right now.
