We have never been to Vienna and unfortunately, we'll only be there 2 days. I have reservations at Steirereck, but I'm wondering if we should devote an entire evening to dinner there or if it would be better to eat elsewhere and devote more time to sightseeing? Is it really, truly amazing and worthwhile or are there other places that are just as or almost as good without the hype? I've seen some mixed reviews on Yelp, so I'm not sure. Also, my husband will not wear a jacket, so will he be out of place with dress pants and a button-down shirt? Thanks in advance for your help!
