BRADENTON, FL—Hannah Robles, 3, shrieked in terror Monday when a Bennigan's waitress brought her father a plate of audibly hot Super Sizzlin' Fajitas. "Those fajitas really startled Hannah," said Evan Robles, 35. "I'm not sure if it was the sound of the fried onions angrily crackling in their 500-degree juices or the heat-distortion waves rising off the cast-iron skillet plate, but she just freaked."
