Not bad.
I go here to order Tapsilog specially on rainy days when I'm feeling particularly homesick (Philippines homesick) and it brings me right back to where my heart is.
As far as customer service and dine in experience goes, well it will all depend on what you expect. I don't think this is where their effort lies in as much as they do the authenticity of their products.
Authenticity? Product and foodwise - they've pretty much got it down perfectly.
