I have high expectations when it comes to Indian cuisine because I grew up on it... homemade.
I've been to this restaurant 3 times over the last 8 months. The first 2 times we all ordered the Masala dosai. From the first visit to the second there was a big difference in the dosa texture, color, thickness and flavor, the fillings and the sambher soup it comes with. Each person at the table ordered different levels of spiciness yet all of the dosa and soups were made the same level. Oh well, I still ate it and it was delicious. Dosa are large so I took home leftovers...it was even spicier than the day before. In my experience this is usually the case with Indian cuisine.
On the third visit I was tempted to order another dosa to see what it would be like the 3rd time, but we arrived in time for the buffet. There were many choices and the room was packed! I enjoyed all the vegetarian options from chana masala and mattar paneer to malai kofta and dal. Plus they had amazing desserts...burfi! No one EVER has burfi! Of course I had the obligatory gulab jabun too!
The service isn't the star at Taj Mahal...the food is. If you keep that in mind and enjoy the cuisine you will come away satisfied. We will be back! Maybe for the buffet but probably for another dosa!
