Cosi is one of the 30 restaurants included in the 30% discount booklet Restopass, located in the popular Chatelain neighborhood and thus, subject to a lot of tough competition since the area is full of fairly decent eateries.
The lowdown: Ok meal but not spectacular. You can do better for the same price in Brussels but the service is friendly and it’s fine for a night out with friends.
The restaurant has a casual, relaxed atmosphere and has two rooms, one of which is actually a covered terrace that is quite cozy (but can get a bit chilly at night). As an Italian restaurant in Brussels, its food is ok but does not impress much. Prices range from EUR 10 for a plate of simple pasta to around EUR 25 for some of the meat dishes. Dinner for two with a bottle of wine (and no dessert) will probably set you back EUR 70.
They have a decent escalope milanese and the pasta is ok (but if you’re looking for good pasta you can do much better in the neighborhood (try La Piola on Rue du Page)). The wine selection is a bit disappointing as they only have a limited selection of reds (without providing many details on the menu) and very few whites.
