I've been to various Taj properties over my career life, and Trattoria missed out on my list for the longest time. I did finally manager to make it there for a quiet lunch one fine day, and did not come back much impressed.
The ambience, is like sitting in any Taj restaurant so that was not so much a differentiating factor. The food was good, except for the maincourse. I've never had a pizza which had raw leaves all over it, and I don't even want to remember the name!
Out and out, a dissapointment!
