I have a severe life threatening nut allergy; I routinely advise the waitstaff of this and ask them to warn me if I order anything containing nuts,or nut oils. Although I told our waiter at Halcyon all of this, he served me a salad with a popcorn garnish which contained nut fragments. I immediately became sick. Not only was my health put at risk, my husband and I had to cancel our evening and I spent the better part of the next day in bed recovering. And what did Halcyon management do? Nothing other than to casually say so sorry and can we call you an ambulance? I have never been treated with such indifference! For a foodie restaurant they seem to be in love with their food but don't seem to care about their patrons.
