You are allowed to create new scope members inside the expressions.

This lets you assign a filtered list to a new variable, which can be used throughout the local scope. With that, you can pass the length of the filtered list to ng-show:

<body ng-app>
  <div ng-controller="Ctrl">
    <div class="daily" 
      ng-repeat="daily in dailies | orderBy:'-date' " 
      ng-show="filteredEntries.length"
    >
      {{ daily.date | date:'dd/MM/y' }}
      <div class="entry" 
        ng-repeat="entry in filteredEntries = (daily.entries | filter:{ category: 'B'})"
      >
        <span>{{ entry.category }}</span>, <span>{{ entry.note }}</span>
      </div>
    </div>
  </div>
</body>

FIDDLE

Btw, nicely put question!
