A rainy afternoon that never leaves Corydon Avenue
If the forecast turns on you, you don't need to plan a downtown museum run. Corydon Avenue itself has enough indoor stops, all within a few blocks of the Airbnb, to fill a whole afternoon without getting wet more than once or twice crossing the street.
Start with a browse, not a destination
The Cheesemongers Fromagerie (839 Corydon Ave) is a good first stop on a slow, indoor afternoon — a specialty cheese and deli shop that rewards unhurried browsing, and an easy place to pick up something for later in the day.
A sit-down lunch out of the rain
Corydon has several full-service Italian restaurants clustered together if you want to sit down properly rather than grab something quick. Bar Italia (737 Corydon Ave) and Passero Restaurant (774 Corydon Ave) are both a short walk from the deli and give you a dry, unhurried hour or two while the weather passes.
Coffee, then something sweet
Finish at Thom Bargen Coffee Roasters (743 Corydon Ave) for a proper espresso, then walk a block to Sugar + Salt Bakeshoppe (897 Corydon Ave) for cake or a pastry to take back to the Airbnb.
From the Airbnb: Everything here is on Corydon Avenue itself, so there's no transit or rideshare to plan around — just an umbrella for the short walks between doors. Hours can shift with the day and season, so it's worth a quick check of a shop's own site or Google listing before you head out.
