The last time I ate at Karaoke Idol in Falls Church, it was a mixed bag. Four Chowhounds hit this place after a disapponting experience at Elevation Burger to get something interest to eat. Since we had already eaten, we just sampled a little, enough to know that it offered some interesting possibility without the need to rush back.
But of all the Filipino places in the area, this might be one worth investigating. In addition to the best Daing Na Bangus (marinated milkfish) in the area, they also make a mean Dinuguan with pork- this is an amazingly dark, dark, blood sauce. Good noodle soups as well. Lumpia here, as elsewhere, is good if fresh and piping hot.
I went with the kids and they were particularly taken (as I was) with the marinated fish. We had to get another order.
