is there any halal shop or restaurant near to Huxi mosque at Chang de road in Shanghai

There is a halal restaurant near the Changshou Road Metro Station, which is only about 500 meters from the mosque. It is located at no.285, Changshou Road. When you get out of the mosque, you may walk about 370 meters southeast along Changde Road and turn left to Changshou Road for about 120 meters to find that restaurant.
There is also a halal restaurant called Lanzhou Hand Made Beef Noodles Soup located at no.2212, North Zhongshan Road. You may walk about 210 meters northwest along Changde Road and continue 490 meters along Zhenping Road. Then you may turn left to North Kaixuan Road for about 210 meters and turn right to find the restaurant.

thank you for the feedback. I also wonder if there is halal street food around the area. I understand there is halal food market operating between 10 am to 3pm on every Friday near to Huxi Mosque.

Is there any halal food street vendor which operate in the morning(breakfast) and after 3pm at the area?

I just know these vendors will operate on Friday as you already know. I'm so sorry that I have no idea whether they will work at the other times.
