One of the things we knew everyone talked about before heading to Brussels were the yellow wafel trucks that could be found throughout the city slinging delicious Belgian-style wafels. There are, apparently, many colors of wafel trucks in Brussels, but it's the yellow trucks that are supposedly the best of the bunch. So it was that on our way between two of the few touristy spots we actually saw, we came across one of the fabled trucks.
What we ran into was an unassuming food truck that was parked close to the Musical Instruments Museum (the MIM), and we saw a very short line forming since it seemed like they had just parked and opened. We quickly got into line and waited the short bit before getting our wafel.
One thing of note if you've never had a Belgian-style wafel before, the "batter" that is used to make the wafels is much thicker than American-style waffles, and it's also much sweeter. It's more like a cake batter in consistency, and the added sugar helps the wafel exterior caramelize.
We opted for a simple liege wafel with chocolate sauce. Since it was fresh, the wafel itself was very warm and soft. As mentioned, the exterior of the wafel crisped up and caramelized from the sugar in the batter, and the inside was still very soft. You also got a distinct crunch every so often as you bit into and chewed on the sugar crystals in the batter that didn't melt/cook up. The wafel on its own was delicious, but the rich dark chocolate sauce added a divine decadence. High quality Belgian chocolate lent itself to an amazing and rich topping that finished the snack off. We really enjoyed our wafel, and that's definitely one thing we'd try to get again if we ever found ourselves back in Brussels.
