I stopped by for a burger after work one evening. There weren't many people there (it was a bit on the later side) and the staff outnumbered the customers. You can tell this is a new location - the staff are very green. Painfully green. They seemed to be just wandering around the place aimlessly. Two of them just carried on a pretty loud conversation across the counter. It took a while to get my burger even though there were only two people waiting in front of me (their orders had already been placed, they were just waiting). One guy asked whether it usually takes 20 minutes to get your order. The girl looked flustered and said, "Oh, here's your order." I don't know whether it was ready right at that second or they had forgotten to press the pager notifier to let him know his order was ready.
The burger was suspiciously like a frozen patty. I'm not outright saying they do use frozen patties, but that's the impression that I got from this patty. It had that particular plastic-like surface you get with a frozen patty (like a Harvey's original patty). The texture and flavour were honestly no better than Hero Burger, and Hero Burger for me is at the bottom of the heap of overpriced "gourmet" burgers. These people also have a really heavy hand with the mustard. My burger was drenched in mustard.
I might try it again, but my initial impression wasn't that favourable.
