NAPERVILLE (CBS) — You can still order one shot, one bourbon and one beer at Naperville bars, but you might need to get your order in a little earlier, thanks to new regulations.

Years in the making and spurred on by multiple incidents, which include a recent fatal car accident and the stabbing death of a local teacher, Naperville’s new regulations passed through City Council on Tuesday. For bars, this will mean more restrictions on late-night entry, shot sales and beer sizes.

This comes after a September City Council vote that eliminated deep discounts on beer sales and increased training for bar security.

According to the Daily Herald, Naperville bars and restaurants with liquor licenses will no longer be able to admit patrons one hour before closing time. Closing time is currently 2:00 am on the weekends and 1:00 am during the week.
