I lived in Edinburgh for 10 years but to be honest what with lockdown and some time having passed, I wouldn't be confident what is still there and what isn't, or what is good or bad now.
I imagine the popular places are still popular, the Grassmarket for some good (tourist) pubs, Royal Mile for tartan whisky and shortbread, The Queens Arms on Frederick street is just a right good place for food and drink. Avoid Lothian Road and Leith Walk if possible late at night.
National Museum of Scotland is great, and free, and so is the Scottish National Portrait Gallery, one at each end of the city centre which is quite useful. Right in the middle of the city centre is the Scottish National Gallery off Princes Street.
Pubs. Pubs everywhere. Go to Scotland, drink.
