Just spent the weekend in Portland for the first time - here is the report.
Food Carts - Kargi Go Go is fantastic. Just go there (go go). It's unique, delicious and really quite an experience. We had the 3 item combo, with Khachapuru, Lobiani, and Badrijani. http://kargigogo.com/
Nong's Khao Man Gai - It was hard to believe that a place that serves pretty much one dish could merit such critical plaudits, and I'll even admit that the pictures of the dish online do not exactly help drive the desire to go. But ignore that and GO. It's DELICIOUS. Perfectly poached chicken, a perfectly balanced sauce and delicious broth. Is it revolutionary? No, but they really do deserve all of the effusive reviews. I'm glad I listened. Simplicity sometimes really is an art form. http://khaomangai.com/
Donuts - Our call was that Voodoo donuts were preferred over Blue Star. This is not a knock on Blue Star, the donuts were very good, but Voodoo had that oomph factor so if you must choose 1, choose Voodoo. Otherwise give them both a try.
Urban Farmer - At The Nines Hotel, I can't praise their breakfast / brunch enough. Perfect execution, attentive service, wonderful ambiance, and strong flavors with a Portland influence. The portions are enormous and the prices are startlingly low (in comparison to other big cities, it's a bargain) Their house made chicken breakfast sausage is not to be missed. We ate there twice and I can report that the Crab Omelette with wild mushrooms and pork bits (they don't call it bacon) was superb, as was the house made English Muffin and the potato cake (this is a HUGE plate of food), As is the Brioche French toast with blueberry compote. To start the meal they give everyone house made pumpkin bread with butter so go hungry. It's a great place for adults to enjoy brunch. It was easy to walk right in, so go before everyone else finds out about it. My only criticism is that their website is crappy and doesn't load pages at times. http://urbanfarmerportland.com/
ClarkLewis - we really enjoyed ClarkLewis. Again, excellent service, perfect execution and an interesting menu filled with bold flavors with regional influence. It's also got a great vibe - an excellent destination for an adult dining experience on a Saturday night. The mean started with a fresh arugula salad with spicy salami and shaved Parmesan, then a small plate of perfectly cooked brown butter scallops over a delicious grain, and then cavatelli in a lamb ragu. The menu changes but this is top notch dining that is highly recommended. http://www.clarklewispdx.com (again, their website is really poor in terms of functionality, it loads slow, sometimes to the wrong page, sometimes not at all, but don't let that stop you)
