Final answer:
The nightclub featured in 'The Office' where Dwight, Michael, and Ryan go is a fictional location without a specific name in the show, and it is not connected to the painting 'Bowery at Night' by William Louis Sonntag Jr.
Step-by-step explanation:
The nightclub that Dwight, Michael, and Ryan go to in New York when they visit in the television show The Office is fictional.
It is not an actual club that you could visit, therefore it does not relate to the painting Bowery at Night by William Louis Sonntag Jr. from 1895.
In the context of the show, they simply refer to it as 'the club' in New York. Since the club from The Office is a creation for the show, it does not have a real-life counterpart or specific name that would connect it to the historic art piece mentioned.
