St-Viateur is better, as bagels and as human beings.
Maybe a tough comparison, but was mildly disappointed with the cold, New York-y textured bagel ultimately packaged in bags by Fairmount Bagels. In comparison, the fresh-out-of-the-oven offerings at St-Viateur were transcendant, with slightly crunchy shells giving way to sweet steaming carb flesh.
That said, the bagel with lox and cream was excellent. Compared to NY, sandwiches feature maybe a third of the cream cheese volume, allowing for a more careful taste of the fish and bagel. No onions or capers.
Cash only; Fairmount takes USD, but at an awful 1:1 conversion (versus St-Viateur's rough 5:6?). Bring your loons.
