What are the key factors contributing to the sustained popularity and operational longevity of J & J Kapuso Filipino Restaurant in the context of Filipino diaspora communities? Additionally, how does its menu selection, authenticity of cuisine, and community engagement compare with other longstanding Filipino establishments in similar demographic regions?
I am particularly interested in any studies or empirical data regarding the impact of such restaurants on cultural preservation and economic support in the Filipino expatriate or migrant environment. Insights on best practices in menu adaptation, branding, and community involvement would also be appreciated.
