Dec. 9 is special for Odd Duck, as it’s the day both the original food trailer and the restaurant opened, five years apart. Odd Duck is marking the milestone with another Trailer Throwback Party, this time to celebrate the restaurant’s second year in a brick-and-mortar space.

Stop in throughout the evening for the return of the old trailer menu, which includes Chef Bryce Gilmore’s famous pork belly sliders. The donation at the door benefits Jabo’s Garden at Zilker Elementary School.

Details: 5 p.m. Wednesday. $25 minimum donation at the door. 1201 S. Lamar Blvd. oddduckaustin.com.
