We decided to go to Cafe Castagna for my birthday dinner in early May. The weather in Portland was amazing and we sat outside on the patio, which while right off of Hawthorne was very pleasant and had a cute view of houses across the street.
The food was delicious. We started with a couple of cocktails and a scallop appetizer. Fresh, light, and cooked perfectly. We moved on to the asparagus and egg pizza. The crust was tasty tasty! We finished up with a New York Strip - the fries that came with it were probably the best fries I have ever had a restaurant. Finished with two desserts, a rhubarb and strawberry crisp and a gelato in espresso.
The server was attentive and gave good recommendations on food. Not as helpful when it came to the cocktails, as I wanted something spicy. The first one I had was delicious, but when I asked for a little more kick, she told me she didn't think they could do it. Muddling a jalepeno or adding something (I'm sure the bartender could have advised) would have sufficed. Not a huge problem though - that would be my only complaint.
Go and try it out!
