Shake Shack does day-of-the-week flavors, which change up once a month. August's Friday flavor is blueberry coffee cake: soft blueberry custard with coffee cake mixed in. It's pretty freaking good, and is delightfully redolent of cinnamon (my favorite compliment to the juicy blueberries of summer).
A gin gimlet at Ouest on the Upper West Side. These guys sling the most reliably delicious cocktails north of 59th Street, and I love spending an evening sipping and nibbling - the kitchen sends out regular batches of toasty warm gougeres.
