A liquor license is not only a license to sell alcohol but also to handle it.
Per illinois law:
Licensees may not offer single-priced, unlimited service drink specials or serve more than one drink to a single person at one time. Licensees may not provide free drinks or advertise any of the aforementioned practices. The law allows a licensee to offer a food and drink combination (meal package) for a special price. Refer to 235 ILCS 516-28(c)(2).
You can not skirt around the law by doing this. Even if you could, I dont think you would be able to find anyone to insure you.
