We didn't have to wait for a table, and our food didn't take long to come out.I ordered stuffed flounder and it came with a salad, two very large pieces of fish, potatoes and a vegetable. All that for $19.99, which I thought was a good deal. My husband ordered a BLT sandwich, which was very thick, and he said tasted good. The service was friendly and attentive which added to the enjoyment of our meal. read less

Everything came out very quickly and the staff was attentive and nice.  We will definitely be going back anytime we go out east on the island for pumpkin picking, apple picking, wineries, or just to the outlets. I have even stopped there after golfing at tallgrass or any other courses on sound avenue. read less

My husband Chris and I come here on a weekly basis and we absolutely love the way each meal is prepared and how we are treated from EVERY single staff member!! They all make sure that the food is prepared to your liking and if it is not then simply speak up and they will make sure to quickly get you exactly how you want it prepared!! They truly make you feel like family and are always eager to make for an amazing dining experience! Their recent renovations make for more seating options in an impeccably clean, cozy and well decorated environment! Thank you for having a diner so close to home that we can go to, to truly feel like we are eating in the comfort of our own home!

The great part is that they can make most menu items gluten free! My wife has celiacs disease and mentioned it to the waiter and he told us they actually have many gluten free options which is great because she has celiacs disease and cannot eat wheat. Wonderful food and friendly. Will be back! read less

Family owned and operated. Every visit is like meeting friends.
Great food warm and friendly staff make this place a win every time.
Just cause everyone is great does not mean there are no stand outs.
The young lady at the counter I call "Greek Island Heather" Knows my order with out being told.
The wonderful selection of fresh homemade soups is great.My favorite is the creme of turkey soup.
The other must is the greek classic pistachio. The creamy béchamel sauce is always perfect.

I can not recommend any place more highly  this is a local gem, you owe to your self to try it read less

The restaurant and especially the bathrooms are always clean. I come here often either alone or with friends and have never had a disappointing meal. I also recently attended a surprise birthday party catered by Greek Island Diner and the food was amazing! There was a make-your-own Greek salad bar with all the fixings, and a variety of hot and cold foods. Truly delicious and plentiful! Consider them for your next catered party! read less
