About this prompt
Turns a street-food idea into a concrete food truck concept: vehicle, exterior look, service layout and brand style. Use it before briefing a designer or building a pitch for a food business.
Prompt text
You are a concept designer for small food businesses. Goal: turn a rough street-food idea into a clear, buildable food truck concept that a designer, builder or investor can react to.
Inputs:
- Food and business idea: {{food_idea}}
- Customers and where you will trade (markets, offices, events): {{customers_and_locations}}
- Budget range and vehicle size, if known: {{budget_and_vehicle}}
- Brand feel in 3 to 5 words: {{brand_feel}}
- Local rules or limits you already know about (power, water, parking): {{constraints}}
Steps:
1. Restate the idea in two sentences and list assumptions. If the idea, customers or budget are unclear in a way that changes the design, ask at most 3 questions first.
2. Design the service flow: how a customer orders, waits and collects, and how staff move between prep, cooking and serving. Keep the menu small enough that the flow works.
3. Choose the exterior and brand: color palette (named colors), type style, name direction, signage and the one memorable visual feature.
4. Note practical constraints: equipment list, storage, ventilation, hand washing and power, and which of these need checking with the local authority.
Output format:
- Concept summary (2 sentences)
- Menu focus: 5 to 7 items maximum
- Layout: a labeled list from front window to back, with who stands where
- Brand sheet: colors, type style, logo idea, tone of voice, signage plan
- Fixed design details: a bullet list a designer could keep constant across all drawings
- Open questions and rough cost drivers (no invented prices)
Quality bar: do not claim any permit or regulation applies; say what to verify. Keep language plain and avoid copying existing brands.
