There is a dry neighborhood in Houston (the Heights) which I don’t understand because it isn’t even a separate city (such as West University or Bellaire or Jersey Village, etc.). Walgreen’s and Kroger cannot sell beer or wine. Restaurants cannot sell beer or wine. Only is the law for a half dozen blocks in any direction but they are large blocks.
Maybe they’re incorporated? There’s a small area near Richardson that is incorporated. Richardson doesn’t sell alcohol, but the incorporated area called Buckingham does. Opposite of your situation.
