Businesses near a Bar
I have found a list of 31 'white collar' business offices in a 500-meter radius of 'The Foggy Goggle' bar, as instructed. The details of all the businesses have been added in the attached spreadsheet.
I used the Oliver Beattie radius tool for Google Maps to generate a circle of 500 meters around 'The Foggy Goggle' bar and then searched through the generated circle for business offices using Google Maps. As per your definition of 'white collar' offices, I have included offices of companies in the area, however, I excluded general locations, e.g. laundromats, restaurants, gyms, parking garages, housing facilities, different types of stores, automotive stores/garages, etc.
I have used the data available from Google Maps to populate the 'name', 'address', and 'type of business' fields for each business listed in the spreadsheet. For employee count, I searched through online databases, e.g. Owler, LinkedIn, Glassdoor, etc., and populated the field in the spreadsheet for the companies for which data was available. For companies where employee count data was not available, I have marked the respective cells with "N/A".
