Brussels' Old Town seems like it came to life out of a fairytale and once you enjoy the fantastic sound and light show against the backdrop of the Grand Place, you will be quite willing to extend your vacations to Brussels by a few extra days.
Before you write off the city as nothing more than a historic stop on the tourist circuit, discover Brussels' sense of humour at the Manneken Pis, a statue of a young boy relieving himself which draws crowds from far and wide, especially on certain special days when the fountain's water is replaced with beer or wine. While museums for art, sculpture, and even musical instruments, can be easily found throughout the city, stop by the Comic Strip Museum for a glimpse of something a great deal more unusual.
There's no place better then Brussels to try a large bowl of moules-frites mussels cooked in white wine and served with fries. The meal is hearty, cheap, and quite an experience to eat as you pluck the mussels from their shells. Remember to leave some room for some of Belgium's famous chocolates and a large mug of Belgian beer to wash it all down with.
