Location: On the main, right next to Sparrow. Street parking available [metered] and the closest subway is probably Laurier or Mont-Royal. Alternatively, you can hop a bus from downtown - I think the 55 (or maybe it's the 51) that runs the length of St. Laurent.
The place: Location on the 2nd floor of the building, Cardinal actually has two levels so be prepared to climb some stairs. I loved the space and the old-school decor - it's the perfect place to cozy up with a book while enjoying tea and scones.
The goods: I defeated the purpose of visiting a 'tea' room by ordering the lemonade + the egg & cress sandwich. After walking around most of the day, I was feeling too warm for something hot SO I guess I'll just have to go back! The lemonade was very good and definitely tasted home-made. It was very tart with a hit of sweetness - just the way I like it. The egg & cress was served on a thick slab of bread and topped with arugula. I'm not super crazy about egg sandwiches but they were out of the avocado toast and this was my back-up. Quite surprisingly, the egg salad was delicious, as was the bread. For me, it was the perfect size because the bread itself was quite filling.
Service: Good. We were seated immediately and the hostess let us pick our table. There was a bit of a mix-up when it came to the bills, but this was sorted out right away.
Price point: About $10 for the lemonade and sandiwich.
