Every restaurant has a wall of laminated permits near the kitchen door, and each one represents a different regulator who can close the place. This article explains what that wall actually is. It covers the licenses required before a single plate goes out, the health inspection and what a score really measures, the liquor license and the three-tier system that makes it so oddly valuable, the tip credit that makes restaurant payroll unlike any other, food safety and allergen duties, menu labeling, the delivery platform contracts that quietly reshaped the industry, dram shop liability, and the lease that outlives the business. It ends with the failure modes that close restaurants.
