From the early morning rush of pineapple buns to late-night bowls of satay beef noodles, the cha chaan teng (Hong Kong-style tea restaurant) is the undisputed heartbeat of the city’s culinary identity. While these no-frills eateries are woven into the fabric of daily life, their architectural and social intricacies often go unnoticed. A new multi-disciplinary exhibition at Airside’s Gate33 Gallery aims to change that, inviting the public to examine the “invisible designs” that make these institutions unique.
Running until July 31, “The Cha Chaan Teng Codex: Tales of Invisible Designs” is a deep dive into the history, aesthetics, and operational science of the city’s favorite dining spots. Curated by architectural historian Charles Lai and product designer Kay Chan Wan Ki, the exhibition brings together a diverse collective of architects, filmmakers, and chefs to dissect the anatomy of the local cafe.
Exploring Seven Chapters of Local History
The exhibition is structured as a narrative journey across seven distinct chapters, each focusing on a different facet of the tea restaurant experience:
- Historical Artefacts: Visitors can view rare memorabilia, including original 1951 business licenses from Yuk Woo Cafe and the iconic neon signage of the now-closed Sun Fung Kee in Wan Chai.
- The Anatomy of the Booth: A detailed reconstruction of a vintage cafe interior showcases how local carpenters adapted mid-century Nordic furniture designs using regional materials, creating the high-backed booths that maximize space in Hong Kong’s dense urban landscape.
- The Nerve Centre: A full-scale recreation of the beverage station—the high-pressure “engine room” where silk-stocking tea is pulled—demonstrates the hyper-efficient organization required to serve hundreds of customers per hour.
- Sensory Science: In perhaps the most experimental section, the exhibition deconstructs the chemistry of classic egg dishes. An interactive olfactory installation also allows visitors to experience the specific aromas of soy sauce chicken and curry beef brisket.
High-Stakes Hospitality
For those who have always marveled at the speed of local waitstaff, the exhibition offers an interactive challenge. Visitors can test their skills in a digital game that requires memorizing and transcribing shorthand jargon. From “C0T” (iced lemon tea) to other cryptic abbreviations used by servers, the installation highlights the sophisticated linguistic efficiency required to keep a cha chaan teng running smoothly.
Cinematic and Modern Perspectives
The final chapters bridge the gap between tradition and modern culture. The exhibition explores the role of the cha chaan teng as a cinematic backdrop, featuring insights from filmmakers on why these spaces have been essential to Hong Kong cinema since the 1980s.
To conclude the experience, young local artisans and chocolatiers offer contemporary takes on classic flavors. The retail section features whimsical souvenirs, including hand-tufted rugs and plushies shaped like egg tarts and pineapple buns, alongside cha chaan teng-inspired chocolates.
