+There must be major performance problems with performing that many joins in a query. What's wrong with making the default behaviour to grab only the base fields, and documenting that? (except for the fact that subclass-specific methods might break .. hm.) --harmless

 Another option is to lazily load objects like {{{Restaurant}}} and {{{ItalianRestaurant}}} while we're iterating over {{{Place.objects.all()}}}, but that requires a ''lot'' of database queries. Either way, doing this will be expensive, and api should reflect that. You're much better off ''just'' using {{{Place}}}s fields if you are going to iterate over {{{Place.objects.all()}}}
