Lindsay Lohan enjoyed an alcohol-free night out on Tuesday (04.09.12).
The 'Liz & Dick' actress - who has battle drink and drug problems in the past - went for dinner at New York restaurant Rubirosa with a group of friends and family, including her grandmother and mother, Dina Lohan.
However, onlookers say Lindsay was a world away from her former partying days and stayed on the soft drinks all night.
One told the New York Post newspaper: ''She was drinking Coca-Cola, and seemed very coherent and at ease. She kept pulling out this notebook and writing or doodling, and getting up to go outside and smoke.''
While she was behaving herself on her night out, Lindsay was recently accused of trashing Dame Elizabeth Taylor's dressing room trailer.
Angel Alger, the owner of the so-called love nest - where the late actress' romance with Richard Burton started - claims the blonde star and the makers of TV movie 'Liz & Dick', which sees Lindsay play the Hollywood icon, caused up to $100,000 worth of damage when Silver Screen Pictures loaned the property.
She said: ''I was specifically told that it would come back in pristine condition and in even better condition than it was at that time.
''I did not get to enjoy using the lavish French phone that she used or even her personal hair brush that probably still had some of her hair in it.''
However, Lindsay's representative Steve Honig has denied the 'Mean Girls' star had anything to do with the damage.
