Celebrated a birthday with over 20 people attending. Ages of our party ranged from 3 years to 60+, with various dietary restrictions including celiac. When I booked a couple of weeks prior, they asked that I send our entree orders early so their kitchen could ensure everyone received their meals about the same time (and I would think to not disrupt the flow for other customers). It was a huge help not just for them, but for us as well - no need to waste time browsing the menu, just sit down, and enjoy the company. The staff day of were excellent - polite and friendly with attentive service, even with a very busy restaurant. In addition, the food was fantastic, and all dietary needs were met!
Overall, would absolutely recommend Piper Arms Kitchener if you're looking for a restaurant to celebrate any occasion.
