there are some restuarants at PI and DDW that will still be opened at midnight... (PI doesn't close until 2 am)
there is a Shoney's and a Waffle house over on 535 a block or two from the end of Hotel Plaza in LBV. that were 24 hours.
but heck I think I would go visit the grocery store - the last thing I would want after midnight is to leave to find something to eat.....
