This place is such a hidden gem! The food was delicious. Super friendly atmosphere and great service. Finally found a breakfast spot with excellent coffee! While the outside may appear more ' dated ' the food, staff and service more than impressed me. We will definitely be back!!

Don’t judge by the outside, more than meets the eye. I brought my mum here for her birthday and we both loved it. Staff are super nice and will treat you like family. All the breakfast stuff is filling. Go for the french toast! We will be back

Also, sometimes known by its old name Thurstons by folks from the area, this diner is definitely worth it. Portions are generous, prices are very good. Not a lot of 'frills' or alternative ingredients, which is just fine when what you're looking for is basic good food. The sign outside is bleached off (almost entirely white) but if the open sign is lit up they're open and you should definitely stop in. You won't be sorry and you won't leave hungry.

This was SUPER GOOD. Like the gravy the onions & mushrooms with the baked potatoes is so GOOD. You have to make sure you get the baked potatoes. The gravy is so good with the baked potatoes. The atmosphere is so classic too, authentic & classic.
