Grigliato, as I understand is from the same owner as Rendezvous in koramangala, has the same menu - Continental, Chinese & Euro cuisine. I love the steaks, burgers and other knick knacks from the place and the food is pretty delicious ( 8/10) ... 10/10 being my wife and my mom :). The limitations are on the following fronts:
1) Very limited choice for vegetarians (I am not, my wife is, so I care a little)
2) No alcohol except Beer and some Beer mixes (three to be precise)
3) Very slow service, 40 minutes for a fresh lime (yes, no exaggeration), but sweet people
Goods - Food, decent ambience, decent price for the food, a meal for 2 is around 600-700 with drinks.
Overall - place recommended.
