Update again May 21: it was good again today. The fries were excellent, the service was good and my burger was just slightly pink and juice. This is what I want. back to 4 stars. Hope it stays this good.
To summarize my update in one word: inconsistent.
The first time I went here it really was 5 stars. The second and third times it was a 3 star experience (or maybe 2 for the price :/)
2nd time summary: the fries were great but I ordered the smaller burger and it was overcooked. Epic disappointment because the best thing about my first visit was that the burger juiced all over everything. I sort of gave them a buy on that visit because it is harder to cook smaller burgers and maintain their juiciness and everything else was right.
3rd time summary: Fries were WAAAY overcooked and borderline stale tasting (which is weird because I pretty much watched him take them out of the fryer). Fry fail. But! I had reverted to the big burger so I was going to let the fries slide. Unfortunately... my burger was also over done and was kinda of bland/meh. It wasn't bad but it wasn't great.
There is a consistency problem here. Or maybe there isn't and my first opening-day visit was the anomaly (I hope not). But... I'm going to let them get this sorted a bit more before I go back again. I'm not as excited about this as I was when it opened.
Note to everyone about ordering:
Tell them you want a custom burger, and then tell them your toppings. You don't have to do the process-of-elimination ordering that they try to force you into and everyone else here has had problems with. I have never gotten the wrong toppings by telling them 'custom burger, with....'
