Are there any places still open in Hanoi? Can I trust Google Maps when it says AEON Mall is still open?

I spent the whole day bored in the hotel. Today, I took the light rail out and found the streets completely empty—only Highlands Coffee was open. I saw on Google Maps that AEON Mall is marked as open. Should I go there tomorrow for a visit? Tonight, I heard there will be fireworks at Hoan Kiem Lake, but I’m worried there might be no taxis available to get back. It seems AEON Mall in Ha Dong District is also a lively place, and they say there will be fireworks there too. The supermarket downstairs is closed today. I’m staying near the Le Duc light rail station.
