When international investors and regional family offices evaluate a Vietnamese F&B concept, one structural question separates scalable systems from single-store businesses: does the brand operate a disciplined multi-format architecture? In the pho category, the answer increasingly defines which systems are ready for multi-unit and cross-border expansion.
Vietnam’s leading pho franchise category operates four standardized store formats: Flagship (120-200 sqm) for high-traffic brand showcase locations, Standard (60-120 sqm) as the core unit, Kiosk (20-50 sqm) for food courts and malls, and a specialized Airport format with its own cost and pricing structure. For an investor, the format mix is not an operational detail. It is the portfolio strategy.
Because it converts one brand into several deployable asset classes. A single-format chain can only grow where its one footprint fits. A four-format system can take a 150 sqm corner site in District 1, Ho Chi Minh City, a 30 sqm food court counter in a regional mall, and an airport concession, all under one brand, one supply chain and one set of SOPs.
The enabling infrastructure is the central kitchen model. Since broth and core ingredients arrive prepared from a central factory, a kiosk with no cooking line serves the same bowl as the flagship. That consistency is what makes the format mix credible rather than cosmetic, and it is a key reason pho systems built this way compare favourably with chef-dependent Vietnamese restaurant concepts when assessed for franchising.
Flagship (120-200 sqm). The brand statement: full menu, full dining experience, prime high-traffic locations. Highest capital requirement and management complexity, suited to experienced F&B operators or investors with professional management teams. Flagships also anchor market entry, which is why area developers typically include at least one in a territory plan.
Standard (60-120 sqm). The workhorse and the recommended entry for most first-time operators. Large enough to build complete operating capability, contained enough for an owner-operator to control. Multi-unit plans in the category are usually built on a Standard backbone.
Kiosk (20-50 sqm). The capital-efficient entry and diversification tool. Lean staffing, assembly-based operations, and exposure to mall and food court traffic. For investors, a cluster of kiosks across strong malls can spread risk better than one large site, provided each location’s real traffic quality is verified.
Airport. A specialist format with distinct concession economics, tender processes and price positioning. Typically reserved for partners with airport operating experience or the financial standing the environment demands. Pho’s strong recognition among international travellers makes this format strategically valuable in a national or regional rollout.
Three questions matter in due diligence. First, sequencing: which formats does the franchisor recommend for a new territory, and in what order? Second, unit economics by format: how do revenue ceilings, staffing models and rent structures differ, reviewed with real operating data rather than projections alone? Third, expansion rights: how does the franchise roadmap handle a franchisee moving from one format to a multi-format portfolio?
On numbers, expect professional discipline: specific build-out investment by format is shared with qualified candidates in a structured review, not published as marketing figures. The honest public reference points are industry-typical ranges and an 18-36 month payback window. Capital planning fundamentals are covered in our guide to pho franchise capital requirements.
Which format is best for a first international investment in the category?
Standard, in most cases. It builds full operating capability at controlled scale. Kiosk suits investors testing a market or building a mall-based cluster strategy.
Do all formats serve the same product?
Yes. The central factory model standardizes broth and core ingredients across formats; differences are in space, menu breadth and service style, not product quality.
Are airport locations available to new franchisees?
Generally no. Airport is a specialist format discussed case by case with partners whose experience and financial profile fit concession requirements.
