When I visited this building, SWFC undoubtedly is the tallest building in Shanghai. The entrance fee was quite expensive by the way, ranged from 100 - 150 RMB. The employees who ushered us were quite hospitable and they also could speak in English, which is really fortunate for us. We went up to 94th, 97th, and 100th floor. At the 100th floor, you could see the beautiful Shanghai from up high. I recommend you to go here at dusk until the nightfall, because the view was especially great, and you could take photos of beautiful Shanghai at night. To take photos, I advise to take photos by SWFC's photo services. Maybe it's a little bit pricey (up to RMB 50 for 1 photo), but it's quite worth it since you wouldn't get a great view if taking photos by yourself.
