I would recommend the two largest shopping centers in Budapest, Mammut, and WestEnd Centre (which is located right next to one of the two main train stations) The main "exclusive" shopping district is called vaci ucta, which has high end clothiers, it is at the deak ferenc ter stop on the 3 line, or vorosmarty ter on the yellow line. As for things to do, I would recommend going to a turkish bath, they are quite nice, and budapest is famous for them, however, I would stay away from the more touristy spas, such as Gellert, which is very pretty but mediocre when it comes to spa activities. The one I would recommend is for men only, it is called Rudas FÃ¼rdÃµ. You may want to take a day trip to Vienna, which has far superior shopping and is only 3 hours away by train. As I lived there for 6 months I can give you far more advice about the shopping in that city if you choose to visit.
