What is the city's side and what do critics say?

A city typically defends a restriction like this by pointing to noise complaints, parking congestion, or pedestrian right-of-way concerns raised by nearby residents or businesses. Critics usually respond that the restriction goes further than needed and hurts restaurant revenue without solving the underlying complaint. Which specific arguments apply depends on the exact ordinance and town in question, so Brian can point you to the actual public hearing record if you want the real detail.
