Hi folks!

I'm stopping by in Dresden in February however, I have a question since I couldn't find the answer using the search.

For the Semperoper, (Opera House) is there a strict dress code? I've never been to any European opera houses and would like to attend one. I generally travel alone and when I do, I travel much like a student - budget style. I'd hate to bring a suit (which I could) but would prefer not to.

Any insights to this? Oh, and any recommendations on where tot eat?

Thanks!
