Absolutely amazing service that actually respects people's accommodations and allergies.
I have celiac disease which means I am unfortunately unable to eat gluten (wheat, barley, etc.) unless I want to get really sick. One time, I ordered the Zac's Big Breakfast here and had asked them to replace the home fries (which weren't gluten-free) with some fresh fruit. They sent in the plate with home fries, and I immediately told them about it. Instead of being very weirdly defensive about it or denying that it had cross contamination (like other diners are around the area), they immediately apologized and gave me a new plate with the fresh fruit instead of the home fries. I came back there a few weeks later, and ordered the same thing. They remembered me and made sure that what I ordered did not have any cross contamination.
Aside from that, the food is pretty fresh and standard diner food. If you like eating out at old-fashioned diners, then you won't be disappointed. The waitress working there with the curly hair is also really nice. The atmosphere can be packed with people and can feel overwhelming for some but hey, shit happens.
This diner has been very accommodating and very understanding for people with celiac disease, which is incredibly refreshing considering the Zak's Diner in Kanata removed gluten-free options on their menu, and I highly recommend this place if you have celiac disease or know someone who suffers from it.
