Given that Pasta Factory is situated in a very touristic place of Amsterdam (and I tend to think that the touristic places around here don't necessarily serve the greatest food..), it took a while until we tried out the place. We were delighted by the quick service, tasty food and good customer service! We've been more than 5 times so far and the food and customer service has been consistently awesome.
If you'd like to warm up with a good soup I'm recommending the chicken soup (best soup I had lately!), and if you're into pastas you should definitely try out (among others) the tagliatelle with mushrooms & cream sauce!
One of my favorite lunch destinations in Amsterdam!
