I've tried this twice - because my first experience was great - the burger was thick, juicy, tasty and done perfectly.
The second time I tried it - NOTHING was right.....the burger was thin, small, dry and overcooked (even though I had ordered the same thing).
I don't know if it was the cook's problem or their lack of training which would establish the necessary consistency for a successful restaurant! Either way, I won't go back.
