I love going to Belgo for quick lunch before my shopping day starts. It 's cheap, it's quick and it's quite delicious too. It has a very relaxed environment, so you can really chat.
I normally go for the musells. I tired the corn-fed chicken, which I didn't like too much. The best part of the meal is the chips. It's so yummy... if you don't mind the calories.. ask for mayo
Last time I went, my friend orders a sausage and mash which actually looked quite tempting.
If you are into beer, they do a very good variety here.
Located below street level.. Excellent selection of Belgian beers, which come in their accompanying glasses (with the exception of Kwak glasses - apparently this caused too many breakages).
