One Flight Up's name refers to its shaded, dog-friendly balcony location, which overlooks the charming storefronts of Donnelly Street while cultivating relaxation with wind chimes and hanging plants. From 8:30 a.m. into the night, the café serves sandwiches, salads, desserts, and drinks suitable for each hour of the day. Breakfast begins with quiches, coffee, and espresso, and then lunchgoers can dig into tomato-basil bisque or a Harvest chicken-salad sandwich. At night, in addition to the food menu, the café's team cracks open beer bottles and pours wines that include Milton Park shiraz and Cortenova pinot grigio.

On weekend nights, live music wafts through the interior and out onto the balcony, twinkling with string lights. Mondays host open-mic performers, who demonstrate their abilities to take a microphone apart.
