Opa is a casual Greek restaurant that doubles as a sports bar. As a result, there's a bit more emphasis on quantity over quality.
That said. Opa offers tasty, shareable appetizers with pita bread, makes good fries (which come with feta cheese sprinkled in top) and the Greek salads are always fresh. Some of the dishes are on the heavy side (eg the moussaka). The best option if you want a lighter meal would be the Opa sauté which comprises a skewer of grilled vegetables plus a skewer of souvlaki (we recommend the lamb).
Quality of bar drinks is average. A serving of sangria proved very generous, a margarita was ho hum, and there was no stemmed glass available to drink a martini (who takes a martini out of a tumbler?).
