Shenanigans at 1 University Plaza will lose three days of alcohol sales and afterwards will admit only customers age 21 and up for at least a year, under an agreement reached Tuesday during a City Council hearing. The three days are technically part of a 10-day license suspension, but with the other seven days waived unless another violation occurs. Alcohol enforcement dominated the regular 9 a.m. council session, which lasted more than three hours before other agenda items were postponed.
