    The person behind the counter makes it obvious he doesn't want to be there. Places next to no lettuce I had to ask him to put more. Uses the tiny pieces and tomato ends that should have been thrown out. I had to change that too as his attitude showed. Mustard and sub source was thrown on like he wanted to make sure I knew he didn't care. Asked for a straw...none. Lazy, bad attitude unfriendly service. Not returning to this location again. Owners need to reconsider their hiring strategy if they want to stay in business

    Love this shop - but lately it’s randomly closed every time I go. Disappointed with the hours and reliability.

    The only Mr sub in Newmarket you have to order from. The rest, especially 18040 Yonge. Stay away from them. You’ll ALWAYS have an issue, they don’t care

    Funny, literally just ordered a Super Assorted. Price on menu was 18.38. How did she enter it, assorted with extra cheese and meat. 11.99 + 8.38. What is that 20.37. I called her on it and she played like it's tax. You guys used to my go too location. Now you are just you lost a regular and will be remembered for shady service.
