I’ve been to the Râle Bol twice now.
It is very conveniently located in the Rue du Page close to Châtelain. Small tables and nice atmosphere inside, a rather small restaurant.
What I like about this place is that it offers lots of cooked options too if you want to go with a group of people and not everybody likes sushi and raw fish.
I wouldn’t say the sushi is the best in Brussels but it is definitely a very good quality (and I am a big sushi lover!). They have nice yakitori as well and a good selection of Japanese drinks and desserts. Prices are very reasonable, not as expensive as other Japanese places in Brussels.
The only thing I missed was the possibility to order little side dishes like Edamame or Seaweed salad. You get a small portion of Edamame as an appetizer, which is nice.
They also do delivery and take-away, I’ll definitely use these services and come back many times in the future. Recommended!
