Where do I find wheat flour?

Sorry that I cant help you but I wish I was your Dutchie sil 

A plenty of Indian shops in & around Brussels. Which area are you specifically interested in ? Here are some of the shops I visit for my Indian grocery shopping.

These shops sell all the brands (Ashirvad, Pillsburry, Shaktibhog, etc, etc) that are famous in India and also some brands sourced from the UK.

-> City Express, Boulevard Léopold III 17, 1030 Schaerbeek, Belgium (very close to Meiser circle)
-> Garam Masala Food Store, 225 Chaussee de wavre, 1050 Elsene
-> Suryansh, Avenue Georges Henri 382, Bruxelles, 1200 Woluwe St. Lambert

They also sell Indian veggies, curry powders, spices, sweets and masalas.

Disclaimer: If you already visited one of these shops and didn't find good atta, I am sorry

Hope this helps.

@ Primadonna, my lady when you come to Brussels you can drop a pm to me - perhaps I can cook for you too

Sorry, I call everyone 'my lady' and 'my lord' these days because I am such a game of Thrones fan

@ Aneesh, how did I miss all these shops, yikes! The most elaborate spice store I could find was called the Khan market, it didn't have what I wanted and the smaller stores neither. I could find everything I needed except some good atta. And yeah, Shaktibhog, Aashirwad and Pillsbury are my favourite.

I hope I'll find these brands at the stores you suggested (fingers crossed). If I do, I swear Imma stuff my face with aloo parathas till I can't breathe

If there are extra paranthas, I can give you a helpline number to clear them out hehe

Yeay, thanks Aneesh, Garam Masala had Shaktibhog!! I am in debt!
