Where can you find good food in Portland? All over the place. I think it's probably one of the best restaurant cities in the country for your average joe on the average budget. Especially if you are vegetarian or an epicure.
Portland is a blessed place in general: excellent public transit, lush forests and gardens, with close proximity to the Oregon coast, the Columbia River Gorge, Mount Hood, the Cascades, and the Olympic Peninsula. This is temperate rainforest country, so yeah, it rains alot, but it is green and lush with plant life.
The city is also known for its many bridges, as it is cut in half by the Willamette River and bordered by the Columbia.
Quick Tips:
Get out into nature. The parks and backcountry are amazing. This is area is constantly embattled over land and timber.
Getting out into it you'll see why: old growth trees almost the size of those in the Redwoods, pristine mountains and rivers.
Best Way To Get Around:
Portland drivers are courteous but drive really slow. There is definitely a small town feel to the driving. You could drive, but the city is easily navigable by bike and public transit (and it's more enjoyable and often faster). It's split into 4 quadrants, NE, SE, NW & SW. The Willamette River splits E and W, and Burnside Ave. divides N from S.
