Bias is defined as the predisposition to one particular outcome over another.

Therefore:

A) Yes, this will likely be a biased sample.

B) Surveying only the food critics instead of random customers may introduce a systematic error because they may not be representative of the whole general population. Moreover, the survey is about an opinion (whether they liked or not the food), and not an impartial evaluation of food.
