What to do in Penza

I moved out of this town over 5 years back. Every time I come back I feel like an observer. And the comebacks are not that often - 3-4 times a year. I don't know that many people as I used to, and all the places keep changing so I can rarely get to the same bar I discovered the previous visit. I find it either closed or renamed or - which is worse - with different kind of public.
But I have my top-7 things to do if you are on a weekend in town.
1. Rent a bike and go in a city park for an hour or two
2. Go ice-skating - closed arena is opened from August till mid June
3. Visit Chistie Prudy area, which is 20 min driving from the city center. They have an amazing park of sculptures, just opened in 2010.
4. Shopping! The best second-hand shops offer all the variety of H&M and Marks&Spencer clothes (a bit used, but who cares) for the cheapest rates on the planet :)
5. Try kebabs Penza-style: everywhere around.
6. Take-away sweets: buy some donuts and cakes from Shokolad.ru and enjoy it out if the weather affords.
7. Go to the recently renovated Drama Theater. I haven't done this so far, but the old one was so good!
