"A popular spot for Montreal power lunches, this restaurant has two distinct spaces: a lively brasserie, and then a more elegant dining room with immaculate white tablecloths on artfully spaced tables. The chef, trained in France by David Zuddas (Auberge de la Charme), draws on French technique and international influences: duck consommé with autumn vegetables, braised duck and barley; sea trout, dashi, daikon, and pak choi. The reference in the name to the migratory butterfly (the monarch) makes perfect sense. At lunchtime, the set menu is limited to two courses, with the option of dessert for an extra charge. Come evening, the dinner offer comprises a four-course set menu. For its use of local ingredients and aged meats, such as beef from Prince Edward Island, and good selection of local cheeses, this restaurant where traditional meets modern comes highly recommended." - Michelin Inspector
