Safe-ish fooding options

Hey guys, back in Dhaka after a long time and looking for some safe-ish street fooding options to check out in the next few weeks where I wont have to worry about kids getting diarrhoea as we all have weaker immune systems compared to before. We dont want to miss out on the food culture as I have been seeing all these food carts popping up almost at every street in the evening but not sure if they are safe for kids.

Preferably places around Dhanmondi, but been hearing about 300ft quite a bit so help a brother out as I am clueless! There are thousands of them and there must a few which are a stand-out or more popular/better.

Also recs on any must have food places, restaurants are most welcome!
