The cities have the ability to add extra licensure requirements, so quotas can and do exist at the city level. Further, there are strange rules about entry to taverns - for example age of entry need not be legal drinking age which differ by city. There are also city or even smaller administrative district rule over what can be sold, pricing rules (e.g. near the college campus there is a rule about the minimum price of a drink special that doesn't apply to a lot of other parts of town) and so on.
