This! I was at Foxtrot yesterday and the lady next to me was having a full Teams meeting in the seating area. I support WFH but people should certainly read the room and be courteous to others.

Joe's Seafood, Prime Steak & Stone Crab. They have some plant-based menu options too.

Pick a museum. The National Portrait Gallery is great and there is a holiday market outside nearby. There are plenty of places nearby to eat also.

Comfortably, no. Rent will be 60% of your take-home pay unless you plan to rent a room. Minimally, you can get by but it will be really tight due to the cost of living or for the occasional fun night out or luxury.
