Help with selecting dates based on time

[John Robertson]

Hey I am new here and new to SQL in general. Basically I wrote a program for work where a user can enter in lunch meal's via php and then the data is displayed on the wall for other workers to look at it through out the day. Higher management wants the meal to display for the current day unless its after a certain time then they would like for the meal for tomorrow to display.

Right now my statement is:
select * from lunch where date = '$todaysdate'

$todaysdate is a variable held with the actual PHP page displaying the lunch meal for that day. How can I add to my select statement where if its after 1PM then tomorrows meal is displayed.
