"I made a reservation for Underhill Cafe a week in advance BUT, the same day of my reservation, they texted me to tell me that they didn 't have space for me, that they had left the OpenTable app open accidentally, and that I could walk in, but they couldn 't promise anything. I wish they had told me this at any point during the entire week beforehand OR had made even a cursory attempt to accommodate my party of 4. Anything!"
