Yes my husband has been a both a presenter and attendee there. It is a massive expo! It has everything from food ingredients to finished food products and it is a world-wide expo. Presenters and attendees will be there from all over the world, and hotel rates are just crazy around that area for that week. I tagged along one year and went to Disneyland of course.

That year my husband was an attendee and logged more steps getting around the show than I did at the parks!
Next year is March 3-6, 2026.
