I should start off by saying that I've been to Al Porto quite a few times, and although the food here isn't particularly special or incredible, their prices are reasonable, the service is great, and the interior of the restaurant is lovely.
The restaurant itself is slightly hidden in Gastown - you have to turn into a very short alleyway to see the door of the restaurant. I think that there's another entrance elsewhere but I haven't found it! The inside is very spacious and the walls are decorated with paintings, there is a very European/Italian feel about it all (although I've never been to Europe, so don't quote me on this).
