Torrance: Ramen Yokocho Festival on 9/14 and 9/15
Billed as the "biggest ramen festival in the USA".
Featuring 12 ramen restaurants and their chefs mostly in your area with 2 from Northern California (Orenchi and Shalala), one from Japan Kitakata Ramen Banmai, Gomaichi from Hawaii, and Monta from Las Vegas).
I only knew about this from seeing the poster inside Sumika Grill in Los Altos (NorCal) because the executive chef Maru-chan is representing Orenchi.
Posting this in case you folks are interested. All ramen $8 flat with free admission and free parking at the Torrance Cultural Arts Center, 3330 Civic Center Drive.
