It's safe to say that every chef has dreamed of telling off a diner who sent back a meal. According to someone who overheard the exchange, this took place at Pilar in Aventura recently:
A woman in the dining room sent back her pasta, telling the food runner it
was "ice cold." The runner tells the chef, and the chef responds by filling a
bowl with ice. He gives it to the food runner and asks him to take it back to
the table. Confused, the food runner asks why. The chef says to tell the woman, "This is
what ice cold is."
