Opa - Waterville

Greek, Mediterranean, Cakes

Nestled in the heart of Waterville, this restaurant offers a vibrant atmosphere and a menu featuring authentic Greek cuisine. Diners rave about standout dishes like pastitsio and calamari, often citing the rich flavors and locally sourced ingredients. However, the experience can be marred by high prices and inconsistent food quality. While some praise the delectable scallops and Wagyu steak, others mention bland seasonings and small portions. Service receives high marks, though challenges with meal delivery occur. Despite the occasional misstep, many patrons express a willingness to return, drawn by the lively ambiance and attentive staff.

Was User at Opa a mag?
Wow, that was my first time trying Greek cuisine! I absolutely loved the pastitsio and orange cake. They tasted truly authentic. Everything else in the restaurant was great, except for one thing - the bill. It was the most expensive meal I've ever had. Although it wasn't my first choice for dinner tonight, I will definitely be back once I save up enough money again. View all feedback.

What User dislikes about Opa:
The food is middle of the road, portions are small and prices are high. Even if I had unlimited money I wouldn't eat here again. It's not that the food is terrible but Waterville is small and you have to do better than average. Especially when it's super overpriced. View all feedback.

I recently enjoyed a dinner at this restaurant and had a fantastic experience. The price per person ranged from $50 to $100, but it was worth every penny. The food was excellent, receiving a perfect rating of 5. The service was also outstanding, with attentive and friendly staff earning another 5-star rating. The atmosphere of the restaurant was lovely, with a cozy and inviting ambiance that added to the overall dining experience. I would highly recommend trying the Lamb Shank, as it was a standout dish.

OMG, the food was just out of this world. The chicken avgolemono soup was so rich. It was the best one I have ever eaten. And the martini was so innovative. We also shared 3 dips with homemade pita (tzatziki, hummus, melinotsalata) and once you've eaten these, you cannot forget them. The olive oil and balsamic dip too was homemade, and what a difference!

We really went all out, app, main meal, two flights of mixed drinks, and a dessert sampler. This meal.was the highlight of our trip to Maine. If you appreciate good authentic Greek food you cannot miss out! Our bar tender on Sunday night was also absolutely a treat.
