The document appears to be notes from interviews conducted at a restaurant. It summarizes the responses of 7 interviewees. Key points include:
- 5 of 7 interviewees mentioned being initially scared by the long line but were curious and came anyway. All said the wait was worth it.  
- Interviewees described the service as friendly and courteous. All rated the service positively.
- While 2 mentioned finding the lack of substitutions weird, the document argues substitutions are unnecessary and could lower service quality given the variety of ingredients in the restaurant's hot pots.
