    I love East Side Mario’s…it’s been my favourite restaurant since I was a teenager. But since I’ve started visiting this location, my experience has been even better! Dillon is one of the best servers I’ve ever had. On my first visit he was so attentive, making great suggestions about food pairings and a new drink to try (the violet ice tea lemonade is my new favourite!), and just generally being friendly, helpful and extremely professional. On my second visit, over a month later, recognized me! He said ‘Welcome back!’, and told me that my favourite table in the corner was free. Throughout my meal, he was the same as before—while also remembering exactly what I’d ordered on the previous visit. He also had exactly the right mixture of leaving me alone (I was reading a book) and checking in to see if I needed anything. I’ll definitely be treating myself to ESM more often now, in large part because of Dillon. I’d give him a thousand stars if I could!

    Went for dinner last night. Was super excited about the garlic festival. My daughter and I both ordered off the special garlic menu. My garlic goat cheese penne came without goat cheese, the garlic was raw and crunchy and my button mushrooms were totally rotten and tasted like actual garbage. The amount of black pepper on my pasta made it unedible. My daughter got the Alfredo garlic pasta and we added goat cheese. Hers also came without the added goat cheese, the garlic was also raw and crunchy. Huge disappointment! Best part of the meal was the bread, and that's free. Service was slow and store wasn't busy. The server was friendly, but didn't check in and we had to leave the table to go find her to ask for the bill after sitting for at least 15 minutes without eating. Didn't ask about refills for soup or salad. Didn't ask if we wanted refills for drinks. My daughter's boyfriend enjoyed his meal, but when he went to use the washroom, it was out of order, so he couldn't go! No other washroom facilities other than the womans, and he didn't feel comfortable, as a man, going in the womans washroom. Next time we will go to Olive Garden in Vaughan.

    This place sucks if you want to be disappointed and dissatisfied this is the place for you the servers don’t even wanna do their job and was more concerned about talking to their customer friends I will never come back and nobody should step foot in that terrible dirty place they call a restaurant they need new staff and learn how to clean and maybe get a hair net my friend had hair in her pasta and hot food poisoning she is actively suing never come here if you want to enjoy good service and good food I’m extremely angry thanks for ruining my evening

    Celebrated my birthday on Canada Day with my son but was not treated right, we didn’t get the warm, friendly treatment that makes you want to go back. It feels like she’s judgmental. I mentioned it’s my birthday, but was ignored. We really didn’t consume the all you can eat soup/salad option as we can’t even finish the first serving, however the bread is fresh & when I requested another server for one, it never got served. I also asked that one Oreo cheesecake be on the dessert plate but she came back with both of them in takeout containers, she said she forgot. She didn’t get a dessert plate & just gave us 2 teaspoons only. I still gave my 15% tip because it’s the polite thing to do, although we’re not happy with the service, I could have given more. My son does not want to come back here, although I told him it’s probably just her. He thinks she’s really rude.

    Visit started rocky with being bounced around from one table to another and then having service take a while to get to us. Another server on her brake basically telling the hostess she was dumb for sitting us in her section while she wasn’t working. But after that initial rough experience we ended up having a great meal and an amazing server by the name of Bella. We went on Tuesday so our two small boys ate free. Bella was sure to make everything top notch after the initial mix up and we will be asking for her next time we go. Over all the experience was decent and we always enjoy a nice early dinner out with our young kids.
