I just had dinner at Carl's Jr! 
Actually tried to have it during lunchtime last week but it's
always packed during weekday lunch hours. So unless you can reach
there before 12pm, do not attempt to have Carl's Jr for lunch
during weekdays.
A combo meal ranges from $9 - $12 (I can't really remember the
prices), depending on the burger you're getting...
Drinks are refillable at all times and the level of service is
pretty good!
And their burgers are HUGE! Makes the BK's and Mac's look like
small fries (pun intended). As for the taste, I can only say it's
very yummy; you got to try it to know it...
Lastly, what they said is true, it's gonna get MESSY...
