HoYoVerse announced it will hold a Zenless Zone Zero Operation Yum event with the characters Ellen and Manato worldwide at restaurants like Kyuramen in the US and Wendy’s First Kitchen in Japan. In every region, it will take place during August 2026, though the promotion does start at the end of July 2026 in Germany and Thailand. So far, virtual rewards are confirmed if you participate, but the company mentioned it will discuss more details later. This means we could also see physical items, such as when the HoYoVerse KFC or Beard Papa crossover events resulted in things like shirts and acrylic stands.

It looks like this is an event where the rewards will be the same everywhere, but the meal and necessary purchases to get the Perfect Taste Bundle of digital goods will vary. People who take part will get a themed Collab Exclusive Commemoration Avatar of Crispyboo the Bangboo, a Namecard with that character, one Stamina Item, three Senior Investigator Logs, and 30,000 Dennies. The announcement also noted a second Delicious Delight Bundel that has a W-Engine Energy Module, two Senior Investigator Logs, and 20,000 Dennies will be offered.

As mentioned earlier, one of the last US Zenless Zone Zero events took place at Beard Papa. That starred Anby and Burnice. More recently, Kura Sushi held a Honkai: Star Rail promotion in June 2026.
