Family-run, brick-walled mainstay serving Greek fare plus pasta, American eats & all-day breakfast.
"There aren’t many Greek diners in Seattle, but Costas is flying the blue-and-white flag. The traditional “American” diner stuff here is solid, but you should come here for the spanakopita, the tzatziki, the bountiful Greek salad. In a neighborhood full of somewhat run-down grab-and-go places, Costas stands out on the Ave for being the kind of place you can proudly bring your parents on graduation weekend. And get bottomless mimomas with them? Sure why not." - Harry Cheadle
