Belgrade & northern Serbia

[GilliC]

Anyone have recs for Belgrade and northern Serbia in early October?

We're headed to a wedding near Novi Sad and will have a few days beforehand. The rough plan is to spend the first day in Belgrade, and then rent a car to spend the next few days exploring with a few friends.

We did a couple of free (tip based) walking tours that we really enjoyed. I can't remember if we used belgradefreetour.com. I think that was it, but I'm not 100% sure.

We also went to the opera one night which was fun. As a bonus, the tickets were really inexpensive.

I'm terrible about remembering where we ate, so no restaurant recommendations.
