The survey has only 2 answers - yes or no - and these answers are non-numeric, and therefore catigorical. Categorical data cannot be represented by a distribution curve so no, the data cannot have a normal distribution. If on the other hand the people were asked to rate the food on a numeric scale (say, 1 to 10 or 1 to 100) you could plot the responses and get a distribution curve, which could be normal.
