Lamesa tries to separate itself from the standard Filipino fare in the GTA and it succeeds, but not by leaps and bounds.
I tried the crispy pata and I highly recommend it-- the portion size is good for 2-3 people and the quality of the preparation is superb (not too fatty, crispy on the right places).
The sisig is a good effort, but the taste falls a bit on the wayside for my taste. Perhaps the odd mix of chicken, pork, and beef (with some egg) deviates from the traditional Filipino approach too much.
And the big disappointment in my books is the halo-halo dessert. I'm not exaggerating in saying that I've tasted better halo-halo prepared in my own home. Their ingredients is not inspiring and folks would be better skipping it.
One final note: I find it curious that the dinner menu doesn't offer too many choices.
As someone who grew up in the Philippines, I think Lamesa puts some interesting touches on the Greatest Hits of Filipino cuisine, and this would be a good choice for people not wanting to go out of the 416 area.
