had an excellent experience that i decided to hunt down the branch in chennai. i was so surprised to arrive there with a plethora of anxious diners waiting to get a table! my friend and i tried to work our way into getting a table by telling that we drove for an hour (which was true!) and that we're foreigners and leaving soon (which was true for me). the lady considered this and gave us a table after about 30mins of waiting.
the grills are great, and i got so full that i never made it to the buffet table. service is ok, we get asked to replenish the grill often that we had to decline after a while.
tip: make sure to book a table!! it's a pain to do a walk-in, they'd even close it at some point.
