Although, we have had one nice sunny morning this past week, I thought I would play it safe this time around and stick to some indoor recreational avenues in Wien. Almost all the districts in the city have shopping centers and theaters, but some of them make for better evenings than others depending on your preferences. In making this list I have also prioritized places that are easier to access using the U Bahn network, so you may see some popular names missing.

1. Lugner City: Among one of the most popular shopping destinations of the city, my first tryst with Lugner was way back in 2009, when I visited the center regularly to visit a really reasonably priced, all-you-can-eat restuarant, which has since shut shop (probably because of gluttonous clientele like me I imagine). However, the place is located close to the inner city (the station next to Westbahnhof on U6) and has a variety of shops, which feature good offers quite regularly and a great food court. Lugner City also has a kino for all you film buffs. Definitely a top destination to shop for some clothes and electronics! Do note that the place can get quite crowded in the weekends.
   

   Lugner City: Great choice of shops and activities

2. Wien Mitte: Billed as the largest shopping center in the city, Wien Mitte is conveniently accessible by U, S and regional train networks. The place boasts of multiple supermarkets (some open even on Sundays), fast food, coffee houses, shops, restaurants and a multiplex. It does not matter if you are looking for books, hats, consumer durables or just a nice place to dine at, this center has it all.
3. Millennium Shopping Center: Located in the lower floors of the Millennium Tower (next to Handelski Station on the U6), this is one of the quieter, more relaxing shopping areas that I have been to. Its right next to Neue Donau, so the view from most places within the center is spectacular. The place boasts of some upmarket coffee houses, a spacious and well maintained food court with a really good variety of cuisines to choose from. As with the other places listed above, this center has a multiplex thrown in as well. It also has a great recreational center for gaming and a disco.
4. G3 Shopping Center: Located at quite a distance from the city, you will need to hop on to the U6 and go all the way to Florisdorf and catch a free shuttle that will take you to the G3 center. While the place is quite far from almost everything, it is quite popular with people looking to do their shopping on a budget. You find a number of brands selling clothes and other merchandise at good discounts and a few coffee shops when you want to take a break from the shopping. It also houses a couple of big supermarkets.

Hope you find the list useful! Please use the comments to add your suggestions to the list!
