Went to watch the Blue Jays ALCS Game 2 here. Sophia, our server, was friendly and attentive. We sat in the bar area (big screen tv) but were able to order from the full, very extensive menu. The dining side also has tv's and booths with personal tv's but the fans were in the bar area. The food was delicious, portions quite big and prices for both food and drinks reasonable.

Don’t let the Sport-Bar-in-a-Strip-Mall look fool you, this place is excellent! We wanted to have a Thanksgiving dinner there, but the day before their Thanksgiving menu was available. The staff offered to talk to the manager and make arrangements for us to order off of the special menu early. Not only were they so accommodating on the phone, but when we got there, our waitress was not only friendly and attentive, but found out about our special order and took care of everything!...

While passing through town we stopped and asked an elderly couple where we could find a decent sit down restaurant. Luckily, we were just up the road. From the service down to the portions everything was top notch! I would highly recommend this place as a stop or a regular treat! It was amazing!
