This is a bit far out from the major sights of Budapest but far better than Westend Mall. Worth spending 2-3 hours looking round here, would be good for a rainy day activity. Free toilet access around the mall.
The temperature of this mall is comfortable, unlike the Westend where they have the heating set to boiling hot in winter! Has some of the same shops, but much bigger versions of those same shops, so there is a greater choice of clothes to choose from.
There are not only fancy expensive brands such as Guess, but also cheaper and equally beautiful clothing in a shop called New Yorker.
There is an abundance of clean and comfy seating dotted about the floors. Some of them are like couch-style.
I didn't bother with any mall-food in Budapest, so I can't rate the restaurants here, but the food court seemed moderately busy when I was here.
