I'm going for work. Staying at the Omni Shoreham. Will be there 48 hours and most of my free time will be in the late afternoon or evening. I've seen the basics one on prior trip (monuments, a couple smithsonian museums). Would love recommendations of things to do later in the day and also restaurants that may be near my hotel. I'm a vegetarian, into local foods and ethnic stuff. My colleagues probably won't be up for straight vegan food so a variety would be best.
Cab or Uber to other areas of the city for food. Personally I'm not a huge fan of that area of DC. Recommendations for DC are:
Rasika (two locations - one in Chinatown, one in the West End) Farmers, Fishers, and Bakers Zaytinya Cava Mezze Founding Farmers Kapnos Mintwood Place (this isn't far from your hotel - also a restaurant that the Obamas apparently love)
