To get to the point, this place is a hidden gem in Waterville. I came here for lunch last week when I was in town to visit the art museum. I selected Opa because of the other great reviews and I like Mediterranean food. I was greeted with a warm welcome as soon as I came in and sat at the bar. I initially got a Greek coffee which was made to order, hot and delicious. Ava, the bartender, was professional, knowledgeable, friendly, and attentive. I couldn't have asked for more. I ordered the falafel dish and was quickly brought a plate of warm bread and olives in oil. Both were outstanding! Looking over the menu, I noticed they had a few Greek wines so I asked Ava about one interesting one that had hints of fig and tobacco. She immediately poured me a sample to taste and it was delicious so I got a glass. My meal came and it too was really outstanding. Every bite was delicious. To add to my experience, Ava put the Bob Ross channel on the TV above the bar so I got my art experience too. Later, the chef came out and talked to me for a while about travelling to Greece to really study the cuisine. He was clearly continuing to immerse himself in the culture to further perfect his already highly skilled craft. I would highly recommend Opa. What a wonderful total experience. read more

We first tried this place 2 yrs ago- it was good food. When I walked in I kept asking for a menu. I asked the bartender- a guy - another girl -- nothing. Then I reasked the bar tender and she was too busy - asked a girl again - never came back. Finally a customer grabbed one and handed it to me . We tried it yesterday- absolutely awful - sorry but -- the meat was super fatty - couldn't chew it - show it to my GREEK friend from Astoria Queens cause she couldn't understand- she agreed- way too fatty -- We dumped it - couldn't chew it. We also ordered spanakopita. We opened it up tonight -- Triangle shaped individual with JUST spinach -- the feta cheese was spread out UNDER these triangle spinach thing (4) super tiny like appetizers- not a meal - no salad either like really? This was a dinner? so very very upset over this food. You will say to me it's was Mothers Day - 9 tables isn't very busy for Mother's Day -- a regular dinner crowd. We expected when we drive 1 hr to this restaurant get great food at a place that almost has 5 stars. I can understand we aren't in Astoria Queens NY but come on - this wasn't hard at all. I waited a whole year to drive back & I really wanted to give a great review but the food was just awful. Very are very disappointed . . . read more

Opa in Waterville was the very first restaurant that was recommended to me to try when we moved to Maine several years ago. I finally got the opportunity to go with my sister and I am so glad! The food is very tasty and fresh tasting. My sister and I ordered several dishes to share. Everything was very fresh and full of flavor. I've never had better chicken kabobs or potatoes. I cannot wait to go back. If you plan on going, I do highly recommend a reservation. We got lucky with walking in. read more

Opa needs to step it up. The food ranges from beyond excellent and totally delicious to eh. The drinks need to be taken up a notch and served in glasses bigger than a thimble. The service is exceptional and top notch. The kitchen crew is excellent. I think the issue is the menu. The ambiance is very very nice. The lamb is over priced and not great. The calamari is very good. The specials are usually very good. The olive oil and bread ranks among the best I've ever had. Roast lamb may be a good item to add. read more

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--10/10. No visit to a Greek restaurant is complete without Tzatziki, and Opa's version stood out with its bright lemony kick. It was refreshing and much less oily than other versions I've tried, served with pita bread--8/10. For mains, we went with the Lamb Gyro, which came on fire-roasted pita with pork blade (an interesting twist), fresh veggies, and creamy tzatziki. Paired with Dodoni feta fries and a demi horiatiki salad, it was satisfying, though the fries could've been crispier--8/10. We also tried their Carbonara, made with angel hair pasta, smoked guanciale, mushrooms, and peas in a rich cream sauce. It was indulgent and flavorful, though super rich--definitely a dish you split or savor in small bites--8/10. To end the night on a sweet note, we had the Baklava, served with bourbon vanilla gelato. The shape was unique, but the flavors were on point--crispy phyllo, warm honey, spiced walnuts. It totally hit the spot--9/10. Final Thoughts: Vibe: 8/10 - Great for families, date night, or large groups Food: 9/10 - So many standouts, especially the spanakopita and salad Affordability: 6/10 - Slightly pricey, but worth it for the quality Verdict: If you're craving authentic and flavorful Greek food in Maine, Opa Restaurant is absolutely worth the trip. read more

YES! I recommend Opa! We had takeout - and we all LOVED IT!!! Online Ordering was a breeze and everything was accurate! No mistakes! It's not inexpensive but it's totally worth it in my opinion. We had and loved the following items: Carbonera $24 Fresh angle hair pasta, smoked pancetta, cremini mushrooms, sweet peas, cream sauce. I added braised pork for an additional $8 - not sure it was worth it, however it was such a decadent, delicious meal. Loved every bite of it. I even shared with others, because they had to know how delicious it was! Pastitsio $24.00 Oven baked, fresh bucatini pasta, beef bolognese, béchamel - YUM!!! Best we have ever had! EVER! I can't wait eat their food again!!! read more

Did a show at the opera house and I found this cute little restaurant. What a pleasant find! I ordered the half chicken and it was delicious. The chimichurri potatoes went really well with the chicken and the chicken was moist and had nice crispy skin. Usually don't order chicken but it was recommended so I went with it. The stars of the restaurant was the service.from the young lady that seated me to the bartender and the other waitress who didn't even serve me everyone was so sweet and just made the experience super welcoming. I appreciate you ladies! read more

Top notch restaurant in Waterville. They had an extensive menu of Greek foods and wine and several selections for those who don't want Greek food or wine. I over bordered because everything looked so good. Each of the dishes was exceptional. There's also an excellent cocktail menu. I will be back. read more

Opa - Prawn Special - Greek Near Me - Waterville, Maine

Recent birthday celebration for a friend . First the restaurant is beautifully decorated. We went in the afternoon so they were setting up for dinner service. They came over and dropped off menus and cocktail selections. While they are pricey they pack a punch. The blackberry kiss was sweet and maybe tasted a little too good as I had two! My friends all sampled and ordered one as well. They brought us warm bread with an olive oil dip. My friends ordered beef meatballs with feta which smelled wonderful. There were enough left to take home. People started coming in and the restaurant has a homey vibe I could also recommend for a romantic dinner. Entrees are pricey but the quality is worth the price. We all need to treat ourselves once in a while. Think of OPA you won't be disappointed l. read more

What a find in Waterville, ME! New Years Eve without a reservation but gladly accommodated at the bar. Ordered off of the specials... Cocktail: Greek 25... Appetizer: 12 Damariscotta oysters with an amazing cucumber jalapeño mignonette... Main: black truffle scallops on risotto with mushrooms. Soooooo good! It was the bar tender's birthday, so they were in a good mood I felt comfortable at the bar since the tables were full of patrons, and I was a single. Was a bit pricey, but everything was perfect and delicious and properly prepared, so it was worth it. One mention... Make sure the oysters are shucked including being loosened from the shell because the restaurant doesn't have small oyster forks. read more

This place isn't terrible, but it is surely not someplace. I would choose to go again. The two meals we had here were both basic and vastly over salted it almost seems that the chef only has two spices in the back salt and pepper. There's so much coarsely ground pepper in my wife's dish that she had to keep picking them out and putting them on the plate. It looked like gravel in her pasta that is not attention to detail that is not care that is un appetizing. The three stars are mainly due to Location excellent service and a fun atmosphere, but you go to a restaurant for food and the food was massively disappointing. read more

So awesome. The owner was our bartender/waiter. He is a great person. Food was amazing. Highly recommend.

We've gone here a handful of times and every time it's wonderful. They have a relaxing environment, attentive and friendly servers, and of course, great food. I look forward to going every time. I strongly recommend the lamb pasta when available! read more

Fabulous food, and perfect service. Josh needs the boss to give him a huge pay raise. His service rhythm was perfectly timed. He anticipated every need. The restaurant was light and pleasant, spotless. This was a first visit, and definitely worth the ride. Nice little gem in the middle of the state. Can't wait to go again. read more

My curiosity about Greek foods was solved at OPA in Waterville. My friends and I visited OPA on Middle Street and were astounded by the presentation of their various choices on the menu. Our chosen appetizers were the meatball plate and a large plate of calamari. The calamari was the best I have ever eaten. The plate included a small dish of pineapple chutney. It pleased one of my guests so much, that she bought two additional orders to take home and share with friends. Our main course choices were : two lamb GYROs and a chicken Gyro. Thoroughly enjoyed by all. I would recommed OPA to anyone who likes a pleasant atmosphere of dining and enjoyable interaction with their waiter. We shall return in the near future to try some of their other presentations. read more

Delicious food, outstanding service. An amazing experience from appetizer to dessert. Definitely highly recommended!

Food was very good, service excellent, unfortunately the restaurant was not well occupied at the time I was there

Fresh and delicious food served here! I found myself in Waterville for the night, and after reading about Opa on yelp, I decided to go try it for myself. The restaurant is lovely, comfortable seating and it was even decorated very sweetly for Valentine's Day. I tried a few things from the menu-the dip trio and the chicken souvlaki. The dips were all so fresh and delicious. My favorite was the hummus! The chicken souvlaki is a pretty large portion and I wasn't able to finish it. I loved how it came with a salad and some roasted vegetables. My friend ordered a side salad and said it was great too. We had more than enough food to share + leftovers. Overall-5 star place! The food was delicious and all the servers were so kind. I hope to come back to Waterville and try this place again. read more

We recently discovered the Waterville Opera House, and this restaurant is just down the road, and was Greek, so we had to try it. I am SO glad we did. The atmosphere is modern, everything is very clean. Tables are a bit closer together than I prefer, so expect to meet your neighbors. The staff are terrific and very helpful. You will need the help to understand the specials, because there are categories of items on the menu that change regularly, which is great fun to try something new, but bummer when you loved the last one. The food is simply excellent. The dishes are creative and not always what you would expect, but the flavors are always well chosen and delicious. The wine list was also had good variety and was not as expensive as other restaurants of this caliber. Definitely give this place a try! read more

Ordered the caprese salad with grilled halloumi, which was burnt to a crisp. Calamari was all breading and extremely disappointing. We ordered two of the weekly chefs specials and could not finish either. The Chilean Sea bass was so overcooked it was mushy, the rice with it was a mix of underdone and overcooked. The zucchini and summer squash seemed to be a day old. The Scallops and pasta dish was overly spiced, which would have been fine if it were made aware on the menu, the scallops themselves were overcooked and burnt, as well as the entire dish soaking in oil. Upon leaving both of us immediately felt sick to our stomachs and we did not even finish the entrees. Hoping this was just a bad experience as we were excited to try this place since we have heard nothing but positive reviews prior. Unfortunately will not be returning after this experience. read more

Great authentic Greek food. The place is spotless and has a comfy modern feel. Service is impeccable, especially at the bar with Parker, who has created a stunning selection of adult beverages. 10/10 would recommend and can't wait to visit again soon! read more

The service was very attentive. The ambiance is fine. The star of this show has to be the food which was AMAZING. We had the grilled halloumi salad which was yummy. The two entrees we had were delicious. I believe the moussaka was the best I've ever had. The bread was perfect and served with scented olive oil. Truly a treat. read more

We had a wonderful dinner at Opa last night. The wine recommendations were excellent. The food was outstanding and the sample dessert tray was perfect. We recommend the lamb, spanakopita, sausage, and the dessert sample tray. Our waitress, Ava, was so attentive and welcoming. She gave us excellent recommendations and we had a wonderful evening full of friends, and great food. read more

The food was fantastic! The service was a little slow, but they had a rush of people going to a concert down the street and it was a weeknight. Seemed to be a little short staffed, but not a problem. The restaurant is fine in regard to decor and ambiance. read more

We were in the area for a small event and were starving when we got out. This location was close and not having Greek/Mediterranean food in a while, we decided to take a chance. We were not disappointed! Great service and the food was amazing! Best falafel I've had in a long time. BF had scallops and he couldn't stop raving about it. Thought he was going to lick the plate. Simply delicious! read more

Small, cozy, and while trying to be an upscale restaurant. Chicken carbonara was over sauce souvlaki was too salty with day-old chicken skewered. I don't want to talk about calamari as an appetizer. I lost to coin toast for this place, but my next dining out would be next door Italian restaurant. read more

Some of the best Greek food I have tried. Look out for when they have the lamb shank special because it is divine. The indoor seating is very cozy and it never gets too loud.

Great food, relaxing setting. Had several smaller plates and really enjoyed the cocktails too! I will definitely go back

Service was nice, staff was pleasant and food was very good. A bit pricier than I was expecting. Drinks were well constructed and served quickly. Small and cozy inside, perfect for a date night. I was disappointed that the saganaki was not available or on the menu at Opa's despite being on the online menu here on Yelp. That might just need to be updated. Overall satisfied and happy to come back in the future. read more

We came here on our way to Boston from Maine. It was a great reprieve from our hot car ride. My friend and I both had the vine leaves with hummus and the aubergine dip. My other friend had the Greek salad with chicken and my husband had the lamb pie. I usually love Greek food but this unfortunately wasn't great. I didn't feel my food had much flavour and my husband said his was quite dry. I wouldn't recommend going here but it's a good option if you're in a pinch. read more
