Best thing to do on a raining day is to EAT!
Au Pied de Cochon, order the poutines & foie gras when you are drunk.
Then go next door to have hand crafted chocolates, Les Chocolats de Chloe.
Eat bagels, 24/7, at Fairmount Bagel.
Have a healthy and super tasty lunch at olive+gourmando.
Finally, a most memorable and fantastic meal at Liverpool House. A must when in Montreal!
