This study explores how ethnic restaurants serve their role as "tourism at home", by investigating customers" motivation to visit ethnic restaurants, especially in relation to tourism. This study adopted a grounded theory approach, using semi-structured interviews composed of two phases. The first phase of interviews was conducted with 18 British people who had experienced at least one of the four ethnic restaurants, Chinese, Japanese, Thai or Korean. The second phase of interviews was conducted with 12 British people who were actually visiting one of the origin countries of those restaurants, Korea, to see if people share the same motivation to visit ethnic restaurants as travel motivation. Six common motivational factors between visiting ethnic restaurants and travel (i.e., to change/ escape from the routine, to experience something new/ different, to experience and learn about another culture, curiosity/ desire to explore unknown, togetherness, and travelling itself) were established through findings, and the relationships between motivation to visit ethnic restaurants and tourism, and how they influence each other were identified.
