    We had a great experience with Nicole at the Newmarket Younge st location. She was so polite, had good energy. She was very encouraging to any accommodations I made. She was quick to check in and get us anything we needed! Brought us extra bread and ensured we had enough salad. The food came out and everything was so hot, fresh and plus we got the Wednesday deal to take home an extra meal for home. Portions were massive, so I had extras as well. Well worth the $. Will be back!

    Our server, “ Sam” was probably the best waitress I have ever had serve my family and I. We dined on a busy night just after christmas. She seemed one step ahead of us the whole time and looked after all our needs and more. Thanks again Sam!!!
