Nob Hill – or 'Snob Hill' to its detractors – has its hub on NW 23rd Ave, a trendy thoroughfare that brims with clothing boutiques, home-decor shops and cafes. The restaurants – including some of Portland's finest – lie mostly along NW 21st Ave. This is a perfect neighborhood for strolling, window-shopping and looking at houses you'll (probably) never be able to afford.
