Cosy's Diner has been a breakfast staple for many Oshawa residents since 2016. I ordered the Early Bird Special, 2 eggs over easy, two breakfast sausages, rye toast, and the coffee is not included with the special but it is decent tasting, hot and endless. First, the service was fast, courteous and attentive. The 2 eggs were for sure large which they don't advertise. The reason for me mentioning this is many breakfast places will advertise 3 eggs but they are usually small. 2 large eggs = 3 small eggs. The 2 eggs were a good size serving and cooked perfectly. The homefries are chunks of potatoes, deep fried and seasoned. They were hot, fresh and crispy on the outside and the center cooked soft. They tasted good and fresh with no ill flavor from the deep fryer oil. Many places have stale dirty deep fryer oil. The breakfast sausages are giants compared to other places. They have a slightly different flavor than the standard mini breakfast sausages but still ok. For me I wasn't a fan but I think many people might really love them, I was just looking for the flavor of the minis this morning. Overall this is a clean neat place that gives you great breakfast value. The service is nice and friendly. I recommend this place to anyone who wants a quality breakfast under $10. Cora's and Sunset Grill can't compete with this place for price/food value. Check Cosy's out next time you're hungry for breakfast and you're in the Oshawa area.

Sunday morning the place was packed with senior citizens which is how you know you’re in for a good deal. Good quality food and very cheap can’t really say anything bad about this spot. Also our server was cute and nice.
