A market research viewing facility is a purpose built venue for conducting focus group discussions and depth interviews. Generally the main difference between a viewing facility and a regular venue such as a hotel meeting room is that the viewing facility will have a one-way-mirror that allows the discussions/interviews to be unobtrusively viewed live by the clients in addition to having built in recording facilities to record the groups/interviews (whereas if a recording was required in a standard meeting room - although possible - it's a little more problematic in that the moderator will need to arrive earlier, set the camera up, ensure it's in a good position, and test the recording).

When using a general meeting room it’s generally not advisable to have a client in the same room as the focus group respondents, as you usually find that the respondents can be put off by their attendance and will not be forthcoming with their opinions.
