Boxplot

This distribution is positively skewed since the upper tail is longer than the lower tail, thus not symmetric. .I would prefer the interquanrtile range to measure dispersion as it is not affected by the skewness

Histogram

The distribution is not symmetric since it is not bell-shaped. The skew is positive/ right skewed. The outlier is trhe value 987.12, which is larger than the average restaurant in this database. It is assymmetrical and positively skewed.
The most appropriate measure of central tendency is the median because this distribution is skewed thus mean would be distorted.
