Nearly lost in a Fountain Valley strip mall, Mel's Diner is more buried treasure than greasy spoon—if you can find it, good things await you. But in the quest for the perfect biscuits and gravy, Mel's is a bona-fide champion. Fresh, fluffy biscuits topped with smoky sausage perfectly cooked (just a little crisp around the edges), and everything's smothered with rich, savory gravy. If sweets are more your style, Mel's cinnamon buns come ooey-gooey and stretching to the edges of the plate.
