Stopped for a quick dinner while traveling. I found the service excellent and the meal delicious. I was thrilled to be able to dine on an omelet for dinner. THe music was fun and added to the atmosphere of a classic diner Will stop in again when in the area

This diner is definitely not your run of the mill Greek diner when it comes to the food. Breakfast here is pretty special, with the best bacon I have ever had.

We heard about this place through a family member and loved it. the menu is extensive for breakfast and the food is very high quality and you can taste it.

Great casual restaurant. Veggie omelette cooked to perfection. Hamburger club with fries - best fries around! Restaurant was busy but our server Sheila was attentive - checking in and ready with more coffee. Couldn't ask for anything better!

Extensive diner menu, good service and great food. Our waitress Amy was knowledgeable, friendly and fun. Although I barely had the room, I had a slice of blueberry pie which was awesome!

We stopped here for a late breakfast (served all day). Pancakes, scrambled eggs, home fries and bacon for me. Good hot coffee. The wife had eggs, hash and home fries with 'when pigs fly' toast.

Best burgers on entire trip. Quick stop on return to Boston. Hot and filling. Glad we came in. The deep fried pickle garnish was a fun surprise and quite good.

Thanks for stopping in your trip. We certainly think our beer battered pickle garnish is the perfect compliment to our 1/2 lb. Angus burgers so we're glad to hear you enjoyed it. Stop in on your next visit! More
