The wait is over! Our autumn menu has arrived, and this time we’re blasting to the past, Y2K style. Join us this weekend for a party at the end of the world.
Saturday, 9/19 we host Double Time (Terry Brooks and Sam Irish) for live music from 9 am to noon.
Sunday, 9/20 we’ll be jamming to Y2K pop hits over the speakers all day.
As always, the vintage vibes will be high with Winnie’s, so come find that perfect Y2K outfit.
We’ll see you soon!💿🐬🫧🦋
