Probably the main bowling spot in Markham? I came with my team from work as a social event and the staff were very accommodating and helpful giving us several lanes in our own section. But definitely not the prettiest of interiors and not a place you really want to hang out at often (unless you are super into bowling) so that's why I'm not giving it more stars.
Bonus tip: if you want lighter bowling balls like a 6 you have to ask at the desk because they keep them separately and not on the floor!
