This is a great and very inexpensive lunch option if you're at Yonge & Eglinton on a weekday.
But this place is hidden in the 2180-2200 Yonge St office building complex. To access it from the subway, walk up the escalator inside the southwest corner foyer at Yonge/Eg and then walk down the hall, it'll be on your right. To access it from Yonge Street just south of Eg, enter the building next to the Rogers store, walk up the stairs and turn left.
Anyway...
Along with sandwiches (good BLTs) she makes several hot lunches and a soup every day, and they're all homemade, very yummy and VERY reasonably priced. Expect to find: jerk chicken, beef stew, schnitzel, lasagna, butter chicken, stuffed peppers, butternut squash soup, chicken vegetable soup.
The prices are amazing and the food is delicious.
