I've been to BRGR before, but made a recent trek on a Wednesday after work. It was a pleasant surprise that there was no wait. On prior trips I've gone on the weekend and had to wait longer than Kim Kardashian's marriage.
We were quickly seated and our server was very friendly. For some reason, I wasn't feeling terribly adventurous tonight and decided to just get the Average Joe with feta bacon and a side of fries.
The food came out and looked great, but my burger seemed out of place on such a large bun. In prior experiences I hadn't noticed this because it was covered in so much other deliciousness (see the short ribs on the button buster). The food tasted ok. The burger wasn't bad, but it wasn't great either. The same can be said for the fries as well.
Overall, the food at BRGR is decent, but it's probably not going to knock your socks off, especially compared to some of the other burger places in Pittsburgh.
