shell programming and scripting

hi,
i am trying this while loop and i only want that it should only read food as pizza....no other entry should be taken here.

Code:
#!/usr/bin/perl -w

$food = " ";

while ( $food ne 'pizza' )
{
  print 'enter what you had last night: ';
  chomp ($food = <STDIN>);
  #print $food ; 
}

print "Mmm....it was yummy \n";

this is what the result i get after running this particular script, that the loop does not end and tht i have to terminate the session.
Code:
enter what you had last night: mango 
enter what you had last night: pizza 
enter what you had last night: tomato 
enter what you had last night: potato  
enter what you had last night:

this loop dpes not end as the way it should have ended.

thanks
kullu
