Good work. Your API implementation looks great; I can't find any problems. There are a few issues with your RDFa, mainly having to do with confusion about how to properly use the BBC Food Ontology:

* A [`bbc:Collection`](http://www.bbc.co.uk/ontologies/fo#terms_Collection) is a group of recipes, not a group of menus. I would just use an [`rdf:List`](http://www.w3.org/TR/rdf-schema/#ch_list) here. See sils-webinfo/WIO-restaurant@f40ce17
* You only use `bbc:side_dish` to relate menus to the dishes they contain; instead you should store your information in your `data.json
