FAQs, Turning 18 in Illinois

Do Illinois chains require ID for the free birthday drink at age 18?

18-year-olds in Illinois can claim every non-alcoholic birthday freebie at national chains. Birthday drink offers are gated to 21+, so they don't apply at this age.

Are there Illinois-specific birthday freebies that don't exist nationally?

Yes. Illinois (and Chicago specifically) is home to Portillo's, Lou Malnati's, and Garrett Popcorn — each runs a sign-up birthday offer that stacks with the standard national lineup. These regional offers stack on top of the national chain birthday programs, so a typical Illinois birthday haul is bigger than what a national-only checklist suggests.
