My husband and I will be in Montreal next week with our 2 1/2 year old twins. Eating in a restaurant with them is not very pleasant. We'd prefer to grab take-out for all of our meals. Olive et Gourmando seems like a great place for lunch but can we just walk in and order a few sandwiches to go or is it a sit down formal type of restaurant? In other words, do most people sit and eat there? Would the service be quick like in a bakery or deli or would we have to wait 20 minutes for a couple of sandwiches?
