Hi Saasha Yes you can buy the ticket online. Please google for Hanoi Opera house, there was an online website with shows schedule. There are some guidelines in TA that we need to abide. So cannit list down here.

Hi, You can google Hanoi Opera Tickets. Or, if you are staying at a major hotel ( Sofitel is the best ) the Opera House is literally twp blocks away and you can walk there to get tickets.

I got it at the hotel I was staying at.

I think you have to go to a show but there is a bar so maybe during show times you will get in. Hope this helps. Others enjoyed the show we didn't rate it.

We went to the Opera and the dress code was relaxed which was a relief. Smart casual is fine (I only had black jeans and a shirt as we are on holiday from the UK and that was fine). If you wanted to dress up more then you could. Up to yourselves. Its pretty cheap ( approx $15 each got us great seats so worth getting a decent seat if your budget allows. Enjoy

Too bad you just missed the only real 'opera' performance of the year last week. The opera house is not constantly showing musical events, so far I do not see anything for 12.2. (try ticketvn website for info, TA does not let me spell out the link) .. from posters around there I sometimes see that the space is 'rented' for private events ... when in the city I recommend to just walk by and ask, as far as I know there are also tours to see the inside. Enjoy Hanoi!
