I quite enjoy the breakfasts here. Actually, I find the food here to be much, much better than Boom nearby on Eglinton (except Boom does make a good smoothie).
Overall, the portions at Sunset are generous and you won't leave hungry.
If you like corned beef hash, order it! I like mine with over-easy eggs on top, rye toast, and fries instead of home fries. Now THAT is a damn good breakfast.
