For those of you who may not know, apparently, Disney has slightly relaxed the definition of "business casual" to now include T-Shirts. I saw this on allears.net:
[FONT=Verdana, Arial, Helvetica, sans-serif]Effective July 1, 2007, Disney modified its Business Casual Dress Code at its premier restaurants to include t-shirts. The guidelines, which originally went into effect July 2005, still prohibit hats, swim suits, swim suit coveralls, tank tops, torn clothing or flip-flops. Suggested attire includes dress shorts, pants, jean pants, collared shirts, blouses, sweaters. Restaurants now requiring Business Casual dress include: Artist Point (Wilderness Lodge), California Grill (Contemporary), Citricos and Narcoossee's (Grand Floridian), Jiko (Animal Kingdom Lodge), Flying Fish (Boardwalk), and Yachtsman Steakhouse (Yacht Club).

EDIT: Sorry, I see Tigsmom beat me to it. I didn't think I remembered seeing that before, but I must have just skimmed the posts previously and missed it.
Sorry for the redundancy.
