If you’ve taken a Saturday or Sunday morning drive down Lancaster Ave., you’ve seen crowds of people lining up in front of Bart’s Bagels. From grabbing an onion topped with nova smoked salmon and pickled cucumbers for breakfast to a classic Reuben for lunch, there are plenty of reasons why the line outside is a fixture in West Philly. Their bagels are remarkably yeasty and deep golden brown, and since they smoke their fish in-house, they have a bagel sandwich list that’s longer than any other shop in Philly.
