Only tried one bun during Vegas StrEATS and it was the Juarez or something... chicken, jalapeno, black beans, etc. It kind of reminded me of the roll things at 7eleven except better and wrapped in a sort of sticky bun. Just based off the one I had, I enjoyed it but I did feel the quality of the ingredients in the bun could have been better.
I look forward to trying more and will update review from there.
