Mitt Romney joins other observant Mormons in shunning alcohol and coffee. He apparently draws the line at ice cream.

The Republican presidential candidate ordered coffee ice cream at Millie's restaurant in Nantucket Saturday when he bought treats for his staff and mingled with diners. His aides selected flavors including vanilla, rocky road, butter pecan and birthday cake ice cream.

It's not clear that Romney took more than a bite or two as he shook hands and posed for pictures in the crowded and buzzing vacation eatery.

Mormons traditionally avoid alcohol and caffeine.

Romney aides shrugged off the selection, saying the candidate can have whatever kind of ice cream he likes.
