This is our favorite Greek restaurant on Long Island. When we cannot get to Astoria, this is we're we go for our grilled octopus.

Celebrated my mom's birthday here. They were so accommodating- gave us a table in the back- didn't mind the balloons and table decor I brought. And accommodated a birthday cake I brought from a bakery. The food was amazing and the service couldn't be better! Thank you for a wonderful night!! read more

Even though this place doesn't look like much from the outside, we were pleasantly surprised when we walked in. Nice white tablecloth tables, a lot of space inside. Food was really good. It was exactly what we wanted. Husband had lamb gyro platter that came with huge caesar salad and I had gyro sandwich with fries. All really good. And only $33! read more

Opa is local for me so it's really convenient. The food here isn't blow-your-mind status but it is solid Mediterranean food. The lunch special is a nice go-to for me. The lamb gyro and the lamb gyro salad is probably the best thing on the menu, in my opinion. Lunch special is great because it comes with pita, fries, salad, and a soup. Incredibly filling meal. A little pricey but not pricey enough to deter me from going back to these guys often. read more

Delicious food. Excellent service. The best Sangria around (with a healthy serving of alcohol soaked fruit). You're treated like family there. read more

Ordered the chicken fillet with rice pilaf and both are dry. There was only 1 waitress serving everyone. It took forever to get the check. Only positive thing is that the food got out quick. We only ate here bc we came from H Mart next door and wanted a quick meal. We should have went to Ayhan's. read more

I love the Opa Grill! Always have a great meal and a great experience here. I live far away and go there whenever my wife goes to the doctor a few blocks away from there. Minor complaint I have, very minor, usually when we are in there there's only one girl doing the waitressing and it is a bit of a longer wait sometimes for service but not enough to lose a star over. Look forward to going there. Lemon potatoes are amazing, Greek salad is amazing, gyro and slouvaki all great. read more

Mediocre food at best, but nice waitress. We had gone a while back and It was good, not great. But it seems like it went downhill. Dips appeared to not be made in-house and chicken was dry and tough. Not going back. Chicken kebab, Shish kebab grill, and Persian grill all far better. read more

Best Greek food around. Clean, and fresh. Highly recommend you to try this place! Workers are very nice too. Easy parking. Not one bad thing to say about this place. read more

the food here is really not that good. I love greek food and have tried many restaurants and I will not go here again. service was good but the food just wasnt read more

Really fresh, delicious, economical lunch! My extended family has always gone to this shopping center for sit-down dinners at Positano's; so now we have two reasons to head over there for delicious, filling meals! I look forward to trying Opa Grille's Bethpage location too! read more

This is probably our 4 th time coming here including throwing my Dads Birthday party here in January. We came at 6:00 no reservation, party of five, seated pretty quickly. Noticed every person coming up to the couple sitting next to us waiting on them hand and foot, while we didnt even have water yet. We order very basic food, greek salad, spinach pie, octopus, gyro, pork cubes w french fries. My boyfriend and sister still hadnt gotten their dinner for a good hour later, the app of octopus came with dinner not before, no sauce for the gyro, never asked if we wanted more soda, water eyc, extra napkins.... Food has always been yummy but theres nothing worse than bad service. I dont know if we will be back, very dissapointing experience. read more

Almost decided against writing as my rating matched the Yelp rating....but it was actually a five star for taste, portion size, promptness, and menu selection - I just felt that the cost was more than warranted. Still the food was excellent - I decided against the chicken souvlaki which is my favorite greek dish (balance of taste and health...kind of), and for what looked like the house special - a dish called the chicken Mediterranean - chicken cutlet rolled around spinach and feta. It tasted very good - although I wouldn't make a habit of that dish as it was a bit too luxuriant. That being said, we will definitely be going back - the salads were great, very fresh, and my wife really liked the spinach pie and grape leaves. read more

Just dreadful - an avoid at all costs place. We were a party of 12 and they failed to prepare food for all of us. 2 of our orders never showed up - no reasons ever given. The manager was rude and arrogant and very unapologetic. What a terrible way to treat customers. Will never be back to this place. read more

The only reason this place is getting a 1 is because of the location in Williston Park. I had given them a 2 previously and thought maybe I should give them one more chance. Man am I an idiot!!!!!! The one day they were completely understaffed that it took 3 hours for dinner for 2 people and the last three times we have ordered from them they have screwed up the order. The girls that take the orders on the phone are inexperienced and make mistakes often, and as I was paying the manager was busy fixing a mistake that someone else had made. They complete forgot my meal after she had repeated the order to me over the phone TWICE for my family. So I'm sitting here waiting for a salad with food getting cold. If you have to eat here DO NOT use this location until the staff gets their act together. They're not even apologetic or give anything in return. read more

There's no shortage of greek restaurants in the Mineola/GC area but OPA grille is the best. Portions are great, prices are reasonable and the service is spectacular. Food is just as good as their Bethpage location. Restaurant is very nice and clean as well. Just wish they delivered.... read more

Did takeout last week. My buddy got the crab stuffed filet and he said it was amazing. I brought home the moussaka with lemon potatoes and it was off the hook delicious. Also had some avgalemono (lemon soup, hope I spelled it correctly) and it was amazing. I was very happy with the value of my meal, and everything was delicious. I will definitely be back. read more

I feel sorry for you if you rate this more than 3 starts and i'm being nice. I would drive to Gyro World in Bayside before every returning here. read more

Staff is friendly and efficient and the food is very good. What else could you ask for. Opa is located in a strip mall with a very large parking lot which is a big plus. read more

We were surprised to find this place located in a strip mall. But, there it is, sandwiched between the Rite Aid and closed Shelter Rock Library. From the moment we walked in, the hostess, server, and busboy, greeted us warmly. We decided to order the Calamari, Chicken Souvlaki, salad, and Falafel. Though the sauces perfectly accompanied the pita, Falafel, and Calamari, I think the chef that night went a bit overboard with the salt. I literally consumed at least four glasses of water, and I was still parched when I left. Also, the food got cold- fast. So, it was difficult having a conversation with a friend while racing against the food clock. I'd also agree with other Yelpers that the place is a bit understaffed, which led to some delays towards the end. However, opa! Onto the next Greek restaurant! read more

Blows all other Greek restaurants in the neighborhood away! The octopus was like butter. Food was fresh, nice staff. They did a great job too redecorating and painting over all those roosters from the previous restaurant. Super new place for willy park! read more

Have been here many times, the spinach pie is great, wife and I split the pork chops which were very tasty. The service is great as always. In short, good food good service and always a great experience. read more

Was here for the first time on Saturday night. The food and service were amazing! ! The place was spotless!!!! Food was the best Greek food I've had in a long time portion was huge staff was very friendly decor was clean and crisp....a must visit if your in the mood for greek! read more

My favorite Greek restaurant. Their avgolemono soup is so yummy. I also love their steak and chicken souvlaki. They also have the best tzaziki sauce. read more

First time trying this place out it was ok don't think I would go back. The spinach pie was really good. The cheese pie was way to greasy and the salad was good but the lettuce had to many of the white pieces of the lettuce. The service was really good. read more

We drive a few miles to enjoy the food here. The lunch menu is unbeatable. Gyros, souvlaki and the filled cheese and spinach pies sing to me, but everything else looks scrumptious. Quick service, but well prepared food and the wait staff is genuinely nice. Complaints about greasy food are unjustified; greek fare typically relies on the richness of good quality olive oil. This place gets busy, but the atmosphere remains civilized. read more

food is decent and eat-in service is good... but for some reason they always have new workers deal with takeout... they do not know what is on the menu and do not know how to pack the food in bag... eat-in and don't takeout read more

Love the place great service. Food was great and portions are very good. I was able to take home to have another meal with my plate that I ordered. My boy friend and I definitely will be back and definitely will be ordering take out and also going back for a sit down dinner again. read more

The food here is delicious! I haven't been to the original restaurant, but will make a point to check it out after my experience here. Ask to sit in Tommy's section. He was great! I happen to love Greek food and I wasn't disappointed. read more

Opa Grille is a worthy addition to the growing group of Mediterranean restaurants in the area. We have been there twice and were more than satisfied both times. The food was fresh, tasty and nicely presented. The decor is attractive. The wait staff is efficient and on both occasions the young women servers had a great sense of humor. Lastly, the pricing is fair. What more could you want! read more

Love Opa Grille. Really good Greek food. Just had the gyro platter, delish. Usually, I order the spinach and feta stuffed chicken with lemon potatoes which is also very tasty. My grandkids love the spinach pie and the grape leaves are also a favorite. read more

bruh i was here with my fam for a holiday and this shit took FOREVER BRO. if you want quick ass greek food don't come here it ain't it chief. it's like they have god damn sped behind the grill for christ sake. it legitimately takes forever. y'all don't come to this joint i told my waitress i was allergic to dairy and gluten and this bitch did not know what it was. read more

Came here for dinner with friends. I had the moussaka and my wife had the lamb chops. Both were very good and the portions were very good. Service was excellent. We will be back read more

The food and service in this restaurant are terrible! It used to be good, but food is served cold and greasy, and one diner ordered a shrimp dish that had such a foul taste that it was completely inedible. It was sent back, yet the charge still appeared on the bill. When the manager was asked by the woman who ordered it to please remove the charge he became incredibly rude! His response was "You ladies are always coming in here and sending things back, and I am sick of it. I will not remove the charge and I don't want you to ever come back here again!" Stay away!!! read more

Decided to try something new for a b-day dinner and so glad we did. the dining room is small so if you have a big party call ahead. We had a party of 7 and we all enjoyed our meals. the teens really liked the sausage and calamari appetizers. the Chicken Mediterranean tender and juicy. The stuffed shrimp should be renamed Shrimp encased in crab meat, sooo good. The lamb chops and the Rib steak looked good and perfectly cooked, but I didn't get a taste for myself. They have a full bar, but try the Greek wine, I had the white and it was really good especially with the lemon flavors. I will be returning soon. read more

I just love it here. The owner(s) are always friendly and present. My daughter loves the lamb chops. The octopus is amazing. Everything is just delish. One of my favorite places. read more

Considering all the great Italian and Chinese restaurants in Nassau County, you would think there would be many more quality Greek places too. Luckily for the folks in northwestern Nassau, Opa is a diamond in the rough. I work in the area and often enjoy lunch from Opa. The food is fresh and delicious. A few of my favorite items on the menu are the Greek salad topped with grilled chicken or gyro meat and the gyro (pita sandwich). The tzatziki (yogurt) sauce is phenomenal. I'd recommend Opa to anyone who was looking to get their Greek food fix. read more

My wife, my son. my daughter and I found the food to be bland. We ordered Pastichio, Mousaka, Saganaki, Avgolemon, Greek salads, Calamari and a Gyro. There was not enough lemon in the Avgolemon, not enough cinnamon in the Pastichio and the Saganaki melted to the point of losing all structural integrity. However, the lemon potatoes were good and the salad was fine. I did not ask the rest of our party if they liked their dishes since I did not want to sour the eveningfor the guest of honor, who did seem to enjoy his fish. read more

I work around the corner and love to get lunch to go from this unassuming little greek place. Despite being in a decrepit, past its prime strip mall, this place seems very clean cut and well organized. The small greek salad is a perfect lunch for me. Also love the that lemony-chicken-orzo soup that all greek places have on the menu, it's awesome here. Hit it up! read more

Service is good and the food is consistently good . My wife and I have come back several times and will continue to do so . They also have takeout . read more
