The canteens and roadside eateries were abuzz with activity as physical classes of DU colleges resumed after two-year hiatus on Thursday, bringing cheers to the owners as well as the students many of whom could bond with their friends over a cuppa for the very first time. As students queued up outside stalls to savour momos, tea, banta, sweet corn and other snacks, business returned to these eateries that had been left cash-strapped owing to the closure of the university due to the Covid pandemic.
