This is how you filter the store

store.filterBy(function(record, id){
    var cat = record.get('category_n');
    if(cat == 'BAR' || cat == 'CAFE' || cat == 'RESTAURANT'){
        return true;
    }else{
        return false;
    }
});

This will iterate each record and will pass it in function, so if you want to check for category_n

EDIT: make sure you clear the store filter next time you load data into the store by

store.clearFilter();
