Restaurant interior style should start from the business model, not personal taste — because the service format dictates how the space is laid out. A buffet restaurant has completely different floor-plan requirements from a fast-food outlet or an a la carte dining room. Below is how to choose a concept for each model, plus the two most popular style directions to shape your restaurant.

Design by business model

Buffet restaurants (self-service)

A standing-service format where guests serve themselves, so it needs generous floor area and wide circulation. Place the food stations centrally and plan the movement flow to prevent peak-hour congestion. Outdoor buffet setups also need protection against dust and weather.

A la carte restaurants

Guests order individual dishes and stay longer, so prioritise wider table spacing and privacy. The layout must be rational enough for staff to survey the room and serve quickly.

Set-menu restaurants

Serving pre-booked groups and delegations at volume. The space should allow tables to be combined flexibly into larger settings; the kitchen needs enough room for many staff working at once.

Fast-food outlets

Characterised by a compact space, simple furniture and fast service. The core customers are young, so use a bright, lively palette; pay close attention to counter and menu layout to optimise speed.

  • Modern: simple lines, bright tones and light wooden furniture — youthful and airy, well suited to a young crowd.
  • Classical and neoclassical: columns, elaborate plasterboard ceilings and warm palettes (white and gold, brass, marble black) — bringing luxury and refinement to upscale dining.

Location and special settings

Beyond style, location and setting type also differentiate: a garden restaurant connects with nature, while a rooftop restaurant trades on views and open air. These models need extra design attention to sun shading, drainage and safety.

Concept chosen — now how do you build it as pictured?

Choosing a style and model is only the first step; the hard part is building it true to the concept, on budget and by opening day. Restaurants carry many technical items that are easy to miss: the commercial kitchen, water supply and drainage, extraction, low-voltage systems and waterproofing. Consolidating under one general contractor keeps schedule and quality under control instead of splitting the job across many crews.

AIC designs and builds restaurants and coffee shops turnkey under a single-point model, with over 10 years of experience (since 2016 under the predecessor Nhan Viet; AIC was founded in 2019) and two in-house factories (1,200 m² and 600 m²) that standardise joinery, counters and shelving. From a floor plan, AIC can produce a BOQ estimate within roughly 4 working hours and writes the opening date into the contract; projects are handed over with a warranty of up to 24 months.

Frequently asked questions

Should I choose a restaurant style by taste or by business model?

Start from the business model and the customer base, because the service format (buffet, a la carte, set menu, fast food) dictates the layout and movement flow. Personal taste belongs inside the frame of the restaurant’s brand positioning.

What does a buffet model need from the floor plan?

Buffets need generous area, wide circulation and sensibly placed food stations to avoid peak-hour congestion. Plan the two-way guest flow (to the stations and back to the table) from the drawing stage; outdoor versions also need weather and dust protection.

Which style keeps costs down for a small restaurant?

A pared-back modern direction usually optimises finishing costs: little decorative detail, light wooden furniture and a bright palette that visually stretches the space. Actual cost still depends on the site’s existing condition and technical items such as the kitchen, M&E and extraction.
