The Mars Diner

What is The Mars Diner? Anchoring Yonge Street just north of Eglinton, The Mars Diner is a classic retro diner preserving the old-school midtown luncheonette tradition. Operated by father Mahesh and chef brothers Anshan and Theiviyan, the compact space is outfitted with checkered flooring, red vinyl booths, and a vintage soundtrack dedicated to 1950s through 1980s classics. Seating is entirely indoors across cosy tables and high-backed booths, maintaining a bustling, friendly, and unpretentious neighbourhood atmosphere.

The Mars Diner Menu & What to Order The sprawling menu leans heavily on griddled comfort food and all-day breakfast staples executed with diner precision. Start with The Classic served with crisp peameal bacon and well-seasoned home fries, or order the hearty Mars Steak sandwich loaded with sautéed mushrooms and onions on a kaiser bun. Pair your plate with a thick, hand-spun milkshake, bottomless drip coffee, or a morning Caesar, and note that vegetarians have plenty of options across meatless omelettes, pancakes, and classic grilled cheeses.

Know Before You Go Service is strictly walk-in only, and while weekend peak brunch hours bring steady crowds, the brisk and attentive front-of-house staff keeps turnover moving smoothly. The diner is situated just a quick five-minute stroll north from Eglinton subway station, with green P street and lot parking available on neighbouring residential side streets. Mars opens bright and early at 7:00 a.m. every day of the week, running through 9:00 p.m. Monday to Saturday and winding down at 4:00 p.m. on Sunday.
