Nihari overnight slow-cooked beef shank stew

None of the three restaurants (Al-Noor, Bawarchi, Pakwan) are explicitly described as serving traditional dawn nihari.

• Al-Noor is a Pakistani restaurant in Lawndale, CA, open Tuesday–Sunday from 11am to 8:45pm ^[1]. Its hours do not include dawn service, and its menu is not detailed in the sources, so it cannot be confirmed as serving dawn nihari ^[1][2].
• Bawarchi is not mentioned in any of the provided sources.
• Pakwan is not mentioned in any of the provided sources.

Additionally, Nihari House in Arleta, CA, is a Pakistani restaurant that serves nihari, but its hours are 11:30 AM–3:00 PM and 5:00 PM–9:30 PM on most days, with no dawn service ^[4]. This suggests a shift to lunch and dinner service, not traditional dawn nihari.

Conclusion: The sources do not provide information about Al-Noor, Bawarchi, or Pakwan serving traditional dawn nihari or shifting to dinner service. To answer the question fully, additional sources would be needed that specify the nihari service times and menu details for these three restaurants.
