I'm visiting stockholm in mid-June for the tail end of the opera season. So I need to eat, twice, in time for a 1930 performance or starting after it ends - I guess at around 2300. Preferably both (though not on the same night). And to do so reasonably close to the opera house or heading into Gamla Stan if after the show. I can't find anything about early/late sittings in recent postings. l have eaten in the opera restaurant's cheaper back room on previous visits (Backfickan if I remember the spelling) and would happily do so again - tho I would rather save it for lunch if the weather is fine. Any thoughts for a late-night option, or alternatives for the early evening - preferably Swedish?
