I generally like technology more than people and I would say the technology here works pretty good. I sat down, reviewed the menu on an iPad, placed my order and paid at the terminal between the tables. It was quick and easy.
It's an airport so the food was over priced but it wasn't actually that outrageous. For a drink, poutine and a 20% tip is was only $15.
The only quibble I had is they charged $3 for soda water and I couldn't even get a refill.
I received my drink and my food pretty quickly. The server didn't really say much so in retrospect, I don't know why I tipped 20%. I'd still give something but probably more like 15% since all she did was put down in front of me and never asked if I needed anything.
