    DOUBLE CHECK YOUR BILL BEFORE PAYING Visited this location on a Tuesday with three adults and one child. The food was decent; however, the service was beyond mediocre. Our server was very forgetful. We didn’t receive cutlery, and despite asking for extra bread, we never received it. Even after ordering dessert, our empty food plates were left on the table. We had to stack the dishes ourselves and then eat our dessert while still looking at dirty plates. When we received our bill, we paid and later realized that we had been charged for the child’s meal, even though kids’ meals were supposed to be free on Tuesdays. We brought this to the waitress’s attention, but she told us that because we had already paid, there was nothing she could do. Overall, it was a very disappointing experience. I don’t want to give this establishment a one-star rating because I understand that it can hurt the business, but I strongly recommend hiring more experienced waitstaff. The lack of service and attention to customers was especially disappointing. I don’t think I’ll be visiting this location again.

    Had an amazing night at East Side Mario's with my wife and kid. We've been here multiple times but tonight was extra special because Richele made it so. She was a delight from beginning to end. The food was wonderful, the drinks were cold and delicious, the service was prompt and thanks to Richele, exceptionally friendly. We will most likely be back again next week since this is our kids favorite restaurant!

    It was my birthday today and east sides Mario's is normally a great place I enjoying going but the service was absolutely terrible. The server when she brought it out the food just slammed my plate down in front of me and my girlfriend as well. She didnt even apologize for it and showed more interest in one of my guests then myself. I also went to go ask her for more bread and she basically shushed me to take a order from my friend. Iam not impressed with it at all. Also the birthday cake was terrible, its so half assed. I understand adults don't really go there for birthdays but everything was terrible for my birthday. I will never return to this location.

    Came for a birthday. Tried the Balsamic Pesto Pizza. Pictures obviously more appealing than what I got. Was still good but it wasn't the best . Paired it with the endless Italian Wedding which was great. The flavor, the meatballs everything was good. Washroom was gross. Had to space my feet apart at urinal so I didnt stand in pee. Dont blame BP for that, some customers are just pigs. Our waitress Kay-something was awesome. Blue hair. She kicked butt. Appreciate the hospitality, and just all around getting everything right and on par. From my 75 year old father in law to my youngest son, everyone was happy with the service and waitress. Thanks

    I met a girlfriend out for dinner tonight here in Newmarket! We planned on coming to East Side’s after seeing the Dine in and take one home special for Wednesday’s as well as the after 8pm app promotion! We were seated in a half booth and table area which was perfect for me, a very accessible and clean section. The restaurant wasn’t overly busy tonight so service was quick and very upbeat from Bella :). She recommended the garlic chicken parmigiana which was delicious, we were able to have all you can eat bread, soup and salad which Bella happily alternated for us without hesitation. She also always made sure we had an enough cheese for all dishes and promptly refilled our drinks when we asked for more! Bella also gave us fresh soup and bread to take home with our to go meal. That was the only thing that was a bit disappointing as we were hoping it would be what you had ordered but upon reviewing the special in store, it was only for three select basic pastas with no protein option. Other than that one small detail which truly wasn’t even a problem because Bella also ensured to fill a small cup of Parmesan for our take away pastas too. To say I am highly impressed with the service tonight is an understatement! Bella was funny, kind, quick, accommodating and even other patrons were thanking her on their way out… just WOW! She truly is a standout and with an incredible employee like that, I hope you are able to give her a little something special for the sparkle she brings to her job, you can see she really enjoys what she does :). Thank you Bella, we hope to see you again and we will ask to be in your section next time too- you rock girl!
