1. Nice use of METHOD OBJECT pattern
2.  Refactor:  REMOVE TEMP VARIABLE (`args`).
3.  Recommender.initialize sets two variables: `@user` and `opts={}`.  Initialize sets `@strategy` to be: `@strategy = (opts[:strategy] || SimpleGooglePLaces).create

Thus:

`@recommendation = Recommender.new(current_user).recommend`
