Concord Family Diner is the epitome of a good mom and pop dive diner. Great food in large portions with a small price. I frequent this place for breakfast a lot. Mostly because the food is great but also because breakfast is served all day. A rarity for Concord. Their home fries are very delicious and very plentiful ( I can rarely finish them). I highly recommend the Farmers Omelet. It's as if you went to your garden and picked every vegetable you had and mixed it in with 5 eggs! Yum!. Other favorites include the Bacon/Cheese Omelet, French Toast and their bacon is even delicious!
For Dinner, I recommend the Broiled Fish ( As my quote states, I like food deep fried... but not always), an unsuspecting treat. I won't quite say that it's healthy just because it's broiled but very tasty all the same. Their burgers are good and so is their other fish entrees. I would steer away from the Quesadillas but to me you don't go to an American-Greek restaurant and expect good Mexican fare. They do offer daily specials (about 10) on top of their vast menu. I have yet to be adventurous enough to try some of them.
Dessert: They have a lot of pies and cakes to choose from. I will routinely get their NY Cheesecake. One slice is plenty for 2 people. They tease you with their desserts in the refrigerated Carousel right when you walk in the door to get your taste buds excited.
I will say that I avoid their Karaoke nights due to the crowd and not so pleasant vocal stylings. Best to avoid those nights and stick to dinner and breakfast.
