Steps
Dataset 4ijn-s7e5, 'Food Inspections', covers Chicago restaurants and other food establishments inspected by CDPH's Food Protection Program from 2010 to present
Query https://data.cityofchicago.org/resource/4ijn-s7e5.json with $where on inspection_date, results, or risk
Join on license_ (note the trailing underscore in the column name) or facility_type against Chicago's Business Licenses dataset for permit context
Parse the violations field as free text - it is a single blob listing all cited code sections and inspector comments per inspection, not normalized rows
Known gotchas
The license number column is literally named license_ with a trailing underscore because 'license' is a reserved word in Socrata's query engine; omitting the underscore returns a query.soql.no-such-column error
violations has no per-violation row structure like NYC's dataset - splitting it into individual violations requires custom text parsing
