Strengths:

• A trial option for a food/beverages/perfume, etc.
• An option for a purchase/consumption simulation module
• Can take up longer vs. interviews conducted at public places (up to 40 minutes)

Weaknesses:

• It is infeasible to get random sampling, thus received data is only conditionally statistically viable.
• The in-hall environment might differ considerably from the typical conditions respondents are used to, thus impacting their answers
• The venues should meet certain criteria (depending on the research procedure/the specifics of tested goods/products).
