If you're not sick of plants (and want to escape rainy weather) - I always love going to Phipps! :) Schenley Park across the street is also a great spot for picnics.
We had our first date here in 2021 - masks and all due to the pandemic!
Since you’ll be here for the NFL draft, there will be festivities in and around Heinz Field if you don’t mind the crowds!
