    Waited 20 minutes after being seated. Didn’t receive any service. Got up and left. Waste of time.

    Overall not a terrible experience. Regardless of having a reservation, the hostess was not around to check us in. I also feel the server could improve on communication as she only stopped at our table once during the entire (although moderately short) evening. My boyfriend ordered the bacon carbonara and lost his appetite a few bites in as the bacon was significantly undercooked. At the time of asking for our bill the waitress asked if we would like boxes, to which we replied no we’re okay, and as there was still a fair amount of food on our plates you would think she would’ve inquired about how everything was or if there were any quality issues, to which she didn’t. Overall, would likely not come back to this location, but the staff did their best.

    Extremely unsavoury experience. We waited 15 minutes for any server to come by. When she did, she dropped off bread, never introduced herself and vanished. Another 10 minutes go by, asked for manager. Table seated 5 minutes after us walked out. Manager came over, no apology, explained waitress was having difficulty…. Manger took our drink and food order, food delivered by another person. Server finally came over.. apologized for mishap.. still unclear what issue was, eventually received bill. We will not be back. Figure out how to manage staff and restaurant operations.

    It was my birthday, i had decided to take me and my friends there, our waitress Tamara was very rude. She stereotyped my whole friend group about the payment methods and gave us one plate for a group of six for appetizers. She didn’t provide the basics of waitressing there, like refillling our drinks and providing straws and grating cheese on our food. We had to ask for it although the other tables she had served were given it right away. She had rushed everyone and threw the takeout boxes on the tables. She was very uninterested when a friend had mentioned my birthday and was only being genuine when we complained to the manager.

    My daughter has loved East Sides for years ao we went tad a family on the weekend. We mentioned to our waitress we need cutlery and we thought she went off to grab us some however she walked by multiple times and never brought any over. I went to the prep area to grab some. We had to ask for bread as she didn’t bring any. The portions are much smaller than they used to be. My daughter’s pasta as barely cooked. My husband and I got lasagna. It was a third of the size it used to be and was not lasagna. It was a layer of noodles with meat sauce and cheese on top. A sad day for East Sides.
