We had Caleb tonight as our server, he was FANTASTIC! We came with two young kiddos after a long day at Ripleys Aquarium and he was nothing short of incredible. So kind and always checking in, chatting with the kids etc. we are from Kingston Ontario and if we lived closer would go back specifically for Caleb!
Thanks for everything

Had a great time at East Side’s celebrating my son’s 5th birthday! He was so excited to see the “robots” bringing out the food they really made the experience special for him. Michaela sang a lovely birthday song, and Evan, our server, was attentive throughout the night.
They even let him spin the prize wheel, where he won a free Chillers drink for our next visit he can’t wait to cash it in! It was a fantastic evening overall. The food was hot and fresh, and the breadsticks just kept coming.
Thank you, East Side’s

Everything was about average, had a noisy kids birthday party. Service was good as was the food. Only lacking was the ambiance. Looked like any other restaurant. Gone are the NY Italian street deco. Which is a downer for me. Gone is the laundry hanging over your head dingy alleys. That was kept them apart from the others and me want to go there.

Had a wonderful dinner with my family this evening. The food was delicious and the atmosphere great, as well as our server Kelly was so kind and helpful. She continued to check on us and make sure our experience was good and accommodating. Why wonderful staff she is, definitely wanna come back because of her! :)

This trip was really an amazing experience for all of us, the food was perfect and the atmosphere made it feel like I was in the most expensive restaurant in the city without the high prices and with the affordability, but what really made the day was our server Amy. It is so refreshing to find someone that takes her job as seriously as she does and has enough patience for others, she really lights up the room with her smile and laughter.
