I've had BRGR 9 twice and it's been pretty darn delicious both times.
The first time, I ordered a burger to-go via the online eatwarehousedistrict service, which I had a coupon for. When I got to BRGR 9, it seemed like they had completely lost my order. Even though no one else was there and there was a bag sitting right next to the register, it took a good 10+ minutes for them to figure out that yes, that was my basic burger.
This meant that by the time I got my burger home (only one block away), it was a bit on the cold side - but was a really good burger! Whew. I was pretty happy with my lunch, and am willing to chock up the confusion to the fact that this was just when EWD was launched.
I then went back on a Wednesday, for 1/2 price burger night. I stepped up from the basics and got a fire burger - I expected it to be really hot and spicy, but I'd say it was more on the "medium" level. The bun got damp pretty quickly from the sauces, but that's fine. I ordered fries and that was a bit too much for me - they'd be good to share with someone else though.
I do think the burgers are a bit expensive if you get them full price, but with weekly half-price Wednesdays, it's easy enough to get them at a discount.
