Back in my hometown in the east coast, Muslims go to the mosque on Fridays for only one reason that is to pray and hear the Friday sermon. They don't go there to eat or to shop. When I first came here to the west coast, people goes to the mosque for that and also to have lunch and do a little shopping at the many stalls set up around the place.
I suppose different places have different cultures. Perhaps the city folks have little time on Fridays to have lunch because of work. Hence the took the opportunity to eat first before going to pray and return to work afterwards.
Anyway the beef soup stalls here is always good. I hope the sellers do join us for Friday prayers also.
