Food was good, the part of our order that was correct! The toast was brought out looking like it was either cut by a blind person or oreo the robot. No one came to follow up to make sure we got everything we ordered our if we needed anything else, or our drink refilled.
The bathroom sinks are pretty cool and oreo the robot server.
When one of the male servers was clearing a table next to us, he turned to ask if everything was OK? I answered no, and he turned around and continued clearing the table.
The manager did finally come to apologize after being asked for him.

Friendly staffAtmosphere
One of my favourite places to drop in for a nice lunch/Dinner. First thing I noticed was comfortable seating area and good atmosphere, 2nd was great customer service, I have been in a few times over the winter when people were not in the best of humour due to cold rainy gloomy weather outside, however the manager has never failed to be friendly and good humoured and makes an effort to talk to everyone that walks in the door he is an asset to the business, the food is fantastic, very tasty, great to have parking outside too nice and easy access. This is a case of its not just the food, it's the people that make the business!
Great food. Started eating before thinking to take a snap. Absolutely excellent fry. Little robot serving people was great to watch.
