There are two "Taj" hotels in Delhi -- actually at least three, but only two are known as "Taj" something in the local lexicon -- and one is the Taj Palace and the other is Taj Mahal (Mansingh Rd). I prefer the Taj Mahal/Mansingh to the Taj Palace but that's not because of the pool; it's because of the location being a decent enough balance. Taj Palace has the better pool.
