THIS PLACE IS GREAT!!!
It's still new and there are quite a few kinks that need to be worked out (ie. service could be faster, wait staff could be more attentive to customers, and any other complaint listed in other reviews) but all in all BRGR 9 is one of my new favorite restaurants!
The menu is fantastic and the food is incredible. I split sweet potato tater tots (yummm!!) and ordered a turkey burger and despite being incredibly full I ate the whole thing b/c it was just that good! They also have an insane selection of beer and alcohol...so drink up!
The place has got a great vibe, too--cool, casual, and chic--that makes everyone feel welcome but VIP-ish at the same time.
I hope they can work out everything that people are complaining about b/c this place is WONDERFUL and has tremendous potential to be one of the hot spots of the Warehouse District.
