The food is solid diner food and nothing is too greasy or buttery, and all served with the biggest smile.  I like gyro sandwiches. 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

This place calls itself a "diner" they have most diner type food, but at regular restaurant quality. Every time I'm here my order comes out in decent time, it's always cooked well, and the food is always good. So if you want really good food at diner prices stop in and enjoy. 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

The food is great, large filling portions. I had the Greek omelet one morning....filled with tangy feta, tomatoes, and spinach and 3 fluffy eggs. Rye toast and home fries kept me full till past noon.
This morning, I had a Belgian waffle with 2 perfectly cooked over medium eggs. The waffle was rich and crispy. Coffee is great as well.
Lots of regular breakfast options, as well as lunch too. And yes, they have Greek food. read less

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
