I've eaten a number of times at Cyma (Shangrila branch) and most of the time, as you said, the restaurant was packed. I guess people are drawn to it because this is one of the first upscale Greek restaurants that opened in Manila so most are curious to see what they have to offer. I've tried their lamb chops and they're tender and moist with a very nice grilled taste.... one of the best i've tasted. They also have a signature dessert with some liquor in it (just slipped my mind what it was called) .... where the waiters would ignite the booze and in unison, shout "Hoppa!" (or something that sounded like that) as they served it the dessert to the eager wide-eyed customers.
