An acquaintance who had cinched a res at Speck's "StudioKitchen" bar for this Friday got an emailed apology Monday morning:
"Unfortunately due to unexpected technical issues regarding some of the equipment we installed and overall construction, we have to delay our opening for six weeks to replace a few things. You are being issued a full refund of the payment you made immediately. In addition for the inconvenience we will be sending you an invitation to come to the opening of Speck Restaurant for a gratis dinner."
Classy way to handle the situation.
