GERTIE is a $ deli and bagel shop with strong signals from both diners and check-ins: a 4.5 Google rating from 201 reviews, plus 2,442 all-time Blackbird check-ins. The crowd peaks on Saturday and Sunday, which matches the review-level evidence: one guest hit a Saturday noon rush and waited about 15 minutes for an everything bagel with schmear.
The strongest through-line is texture and comfort: fluffy everything bagels with a heavy seed crust, whitefish with schmear and pickled peppers on the Yenta’s Bagel, latkes that earned an A+, and an iced latte one reviewer called the best they had in New York. The backyard garden/patio is not a footnote; multiple reviews point to it as a place to sit and rest.
