Angular.js: get different form {{display.value}} and $scope.value from same ng-model

Question

Example form:

<select ng-model="coffee.location">
    <option display-value='Some verbose message here' value="home">At home</option>
    <option display-value='Some verbose message here' value="work">At work</option>
    <option display-value='Some verbose message here' value="chain">Coffee Shop Chain (i.e. Starbucks &amp; Costa)</option>
    <option display-value='Some verbose message here' value="independent">Independent Coffee Shop</option>
</select>

Example display element:

<div>{{ coffee.location }}</div>

---

Question: How can I get my Angular controller to receive option[value], whilst having {{coffee.location}} display option[display-value] (or whatever attribute it need to be)?

I hope my question is clear. Cheers in advance.

What worked (courtesy of @dfsq)

Relevant javascript:

app.controller('SuggestionController', ['$scope', function($scope) {
    $scope.stringMap = {
        home:   'cosy up at home',
        work:   'lounge at work',
        chain:  'patrol the highstreet'
    };
}]);

Relevant HTML:

<div id="some_parent" ng-app ng-controller="SuggestionController">
    ...
    <select ng-model="coffee.location">
        <option value="home">At home</option>
        <option value="work">At work</option>
        <option value="chain">Coffee Shop Chain</option>
        <option value="independent">Independent</option>
    </select>
    ...
</div>

{{stringMap[coffee.location]}}
