Hillwood Estate, Museum & Gardens shared by @infatuation says: ""Booking a group tea at the Hillwood Estate’s Merriweather Cafe is a great move for a birthday. You’ll need to rally a few friends (tea at Hillwood is for groups of 10 or more), but the tea service is priced under $50 a person, making it the most affordable on our list. Once you’re inside, you can roam through the estate, which was originally home to DC’s mid-century social icon Marjorie Merriweather Post. Just know that this tea service doesn’t come with any bubbly, so if you’re hoping to day drink, plan on heading elsewhere after."" on Postcard
