I spent a lovely 24 hours in Brussels, which I found was more than enough time to see all the main sights in the city.
I started the day with a free walking tour, which took me around all the sights and gave me a brief history of the city. Although I didn't particularly like the tour guide I still enjoyed the tour and being brought around the city, and would recommend it as a good way to see the all the sights if you only have a short time.
After the tour I had lunch, then revisited some of the main areas again so I could get more photos and soak in the atmosphere a bit more. Of course the main attractions are the Grand Place (the big colourful square) and the Mannequin Pis (the tiny statue of the boy peeing), both within a moments walking distance of each other.
The most popular places for lunch would be the many places that sell French fries, of course the fries being a Belgian invention that was introduced to Americans by some French speaking Belgians (hence the confusion of the name, although in Ireland we just call them chips).
Weather
Being mid-May the weather was glorious and got as hot as 27 degrees, although I had heard that it usually rains a lot in Belgium and had rained for a few days before my visit. To beat the heat I treated myself to a visit to one of the many gelato places in the city centre, they all seemed to have similar prices and flavours.
Belgian Waffles
As for the waffles - I have a confession. I didn't really like them!! I absolutely love sweet things and had been drooling over photos of Belgian waffles on Instagram in the days before my trip. However I had two - one was plain and I thought it a bit stale tasting, and the other was covered in strawberries and cream from an eatery in Bruges (which is apparently the best), and while it was definitely fresh I still found it very heavy and a bit chewy, not what I was expecting. My sister has a waffle maker in her house and I much prefer the light and fluffy ones we make, sorry Belgium!
After a return to my hostel for a shower I headed out again to the Parlementarium, the interactive exhibit about the European Union, which is of course based in Brussels. They provide free audio guide devices with little screens which you can use to interact with the many exhibits. I was tired and honestly skipped through a lot of it but it's a modern and interesting facility nonetheless and would be a good place to visit while the weather is very hot in the afternoon.
Belgian Beer and Belgian Chocolate
Of course Belgium is also very famous for its beers and there are many bars and restaurants with plenty of space to sit and relax outside, a cold beer in hand. One of the most famous bars in Brussels is Delirium Village, a complex of about four or five different bars ranging from tequila bars to beer, based on the famous Delirium beer, a very strong beer with a pink elephant logo.
There are also many chocolate shops, however you will find that many are for example Leonidas or Godiva and are the same as you can get in these chain stores in your home country, or are tourist traps selling very poor quality chocolate in boxes from China that say "Belgium" on them. It can be difficult to try find a genuine chocolate shop!
Transport
In terms of transport, most of the main sights are within walking distance of each other, but there is a metro, bus and train available. During my visit to Belgium I also went to Bruges, which is just over one hour away by train, so very closeby. You can also get trains to countries like the Netherlands, Luxembourg and France.
