COVID-19, a typical black swan event, not only highlighted the significant and unpredictable challenges faced by the restaurant but also emphasized the urgency of understanding real consumer needs to maintain business continuity and growth. This study employs topic modeling to analyze key aspects of consumer reviews and uses aspect-based sentiment analysis to deeply explore the impacts and long-term consequences of the pandemic at different stages on the restaurant. The research categorizes sentences in consumer reviews into corresponding aspects and emotional categories and examines the specific effects of contingency and information technology strategies implemented by restaurants on customer experience. Through a detailed analysis of consumer reviews, this study aims to reveal the long-term changes in consumer behavior during different stages of COVID-19 and how restaurants can meet these evolving needs through innovative strategies. The study demonstrates how the restaurant can not only sustain operations but also find growth opportunities and show resilience in adversity. The findings not only provide strategic guidance for the restaurant to face future challenges but also highlight the importance of seeking growth and progress in adversity, offering valuable insights for businesses to prepare for similar difficulties in the future.
