I went to one 2 years ago. 

I was greeted by a  gang of temporary foreign workers and tablet like checkout counter.

No thanks. I'm a millennial and I don't care for this kind of "atmosphere".

The burger was overrated. Not bad, but nothing much.

The chilled mug is a nice touch. However, this unique product offering is not a hit when it is dirty. There's a reason most fastfood joints use disposal cutlery and cups.
