This is one of my favorite restaurants in Portland -- Old School Italian with a cosy atmosphere and friendly personal service. It's even a little bit romantic, especially with the live music on Sunday nights. The food is very authentic and delicious, owing the flavors to high quality, fresh ingredients and keen attention to seasonings. My favorite dish is the Pasta Gregorio (spaghetti with walnuts, spinach, artichoke hearts, sundried tomatoes, garlic, olive oil and other wonderful flavors, including white wine maybe). I don't know why the previous reviewer can't enjoy a meal in a place that has a photo of Frank Sinatra on the wall, but Pasta Bella is very clean and friendly, and serves wonderful food at very reasonable prices.
Pros: food, service, ambience, great overall value
Cons: small space, but well utilized. Reservations might be a good idea on busy nights or for a larger group, but my family of 4 has never had to wait for a table yet.
