Denver Broncos defensive lineman Jamal Williams will drop hundreds of dollars to go where the buffalo roam ... as in chicken.
Last weekend Williams and 5 friends rolled into Maryjane's Coffee Shop in the Hard Rock Hotel San Diego at 3 AM ... closing time.
Our poultry spies say Williams -- who just signed a $16 million contract -- promised the staff he'd make it worth their while if they keep the joint hopping so his crew could chow down on burgers, buffalo wings and fries.
Jamal left each of the 6 employees a crispy $100 bill.
He does chicken right.
