★★★★★ 5.0 Mandy Rousselle · Sep 2025

Drinks are great, food is amazing, service is wonderful. Definitely recommend. Went here for my bday dinner and it was so delicious. Had the steak which was cooked to perfection 👌. All the food was delicious, even the yummy dessert they made me! Staff is very friendly and attentive. I will definitely come back to eat here again.

Fabulous lunch at Opa today! We had the hummus to start, it was very good but a bit heavy on the garlic for my taste, but still, enjoyed it very much. I had Moussaka for my main meal - it was rich, flavorful and the portion was so generous I am taking half of it home for dinner. My husband has the gyro and as a gyro aficionado - was able to fully endorse the Opa gyro as top quality! He is also leaving with dinner as the gyro was as big as his head! Our server, Parker, was not only incredibly friendly but impressive in his efficiency. He was the only wait staff when we arrived and it was busy! But at no time did we feel that we were kept waiting nor were we unattended in any way… Cheers to you

This is the absolutely disgusting restaurant ever. I received a stale Carbonara(possibly cooked 3 days ago) and the roasted chickens are smelling nasty. I would suggest that please avoid this restaurant.

Opa Restaurant – Waterville, ME 📍 139 Main St, Waterville, ME 04901 Tucked into downtown Waterville, Opa Restaurant delivers a surprising and unforgettable Greek dining experience in the heart of Maine. From fresh mezze to hearty entrees and indulgent desserts, every dish brought something exciting to the table. We started with the Hellenika Caprese, a Greek twist on the Italian classic. With grilled halloumi cheese, grape tomatoes, pesto alla genovese, and a tangy balsamic glaze, it was light, flavorful, and super shareable—10/10. A perfect start. Next came the Spanakopita (Spinach Pie), and wow—this might’ve been one of the best spanakopitas I’ve ever had. The phyllo was crisp and golden, with just the right amount of feta, mint, dill, and scallions inside. Not too big, not too greasy

Stopped for lunch in Waterville and had a delightful lunch at Opa! We sat on the patio and enjoyed hummus, falafel, grape leaves, and spanokapita. I highly recommend Ihon(?) Tea Pot cocktail, absolutely delicious.
