"We visited Hash House a Go Go about a year ago and absolutely loved it. We were eager to return, so we made reservations, only to receive an email stating that they would no longer be honoring OpenTable. I must have called them 50 times, but all I got was a recording that just said "Hash House a Go Go" before the call ended. I was exhausted trying to reach a person to rebook directly. This situation really needs to be addressed—it feels very unprofessional. I was genuinely looking forward to dining there. We visit Chicago once a year, and I'm very disappointed."
