Can experiential venues generate enough zero-party data to offset RMNs?

In the decentralized-customer-experience, retail gatekeepers like endeavour-group and coles-group monopolize the path to purchase through their retail-media-networks (RMNs) and massive first-party data troves.

To counter this retailer data monopoly, brands are investing in direct-to-consumer experiential venues, such as Asahi’s sumadori-bar-shibuya, which serves as an R&D hub to study the moderation experience and harvest data directly from consumers.

Open Question: Are experiential venues like Sumadori Bar Shibuya capable of generating enough high-quality zero-party data to meaningfully offset the data monopolies of massive retail chains? Or do these venues function primarily as marketing and R&D write-offs rather than scalable data-generation engines?
