Sample Material

Introduction – Two friends are interested in setting up a fast casual restaurant chain in London. The dining concept is “fast healthy Indian” food. They plan to start with one test restaurant and gradually expand the chain. The venture will be funded from their own savings, cash flow generated by the business and bank loans.

Question – What is the market size for fast casual dining in London? Other facts: London population 7.5M, 1/3rd of people age 20-60 buy lunch out, people buy lunch 3x per week on average, average price of a meal 5 pounds.

Basic Answer – # of meals = 3.75M (population assuming equal age distribution 0 – 80 years) x 1/3 (buying out) x 3 (meals per week purchased) x 50 (wks of the year) = 187.5M (approx. 200M)
