For our big Montreal food discovery long weekend, Le Quartier General was definitely our favourite. Two dinner settings daily at 6:30pm or 9pm, and set menus featuring soup/salad, appetizer, main entree and dessert. The serving staff are top notch and will attentively explain everything to you in English so you can make an informed decision, though it certainly doesn't feel like you can go wrong....
Our favourites from the night include the duck foie gras, steak tartare (an absolute winner), marieville duck (perfectly smoky and tender), and creme brûlée (creamy and amazing texture). Best of all its bring-your-own-wine and unlike in Ontario, there's great wine to be found everywhere in MTL.
All in all, this was a lovely 2 hour dining experience and make sure you reserve in advance!
