Yes. The multi-site issue combined with the $19/hr problem prevent the study from being very useful. Given this quote: This pattern of average higher pay and more employment appears also in food services: a decline of about 150 jobs paying under $19 from 2014 to 2016 and a simultaneous increase of about 4,500 jobs in all pay levels at single-site food service establishments. Would you concede the possibility that in Seattle's restaurant sector a higher minimum wage did not have negative employment effects? (NOTE: I edited this question)
