Off to London this weekend, arriving lunchtime Friday and leaving teatime on Sunday. Our Saturday is sorted (brunch, matinee of Dear Evan Hansen and have a table booked for steak in the evening) but the rest of our weekend is unplanned!
Any must see/do's? We have done the stereotypical touristy things before but still definitely London novices coming from the North of Scotland 
Any nice but reasonably priced restaurants for Friday evening? (That won't be fully booked this short notice!)
We are staying in Covent Garden but happy to use the Underground
