Previously, alcohol sales ended at midnight. Sales on Sundays did not start until 1 p.m.
Licenses for non-profit corporations for consumption on premises allows sales beginning at 6 a.m. daily and 9 a.m. on Sundays.
Nebraska City has 35 liquor license holders with an estimated population 18 years and over at 5,361. The density of liquor licenses compared to population is among the highest in the state.
