After hearing good things about Tom's burgers in Markham as one of the best in Markham I would have to agree.
It's your typical Greek owned burger joint, I had the double home burger and it was so massive and juicy. The onion rings were lightly battered, not over greasy.
Only thing is cash only policy but they do have an atm.
Glad I added this spot to my list I'm rarely up in Markham.
