A quick Google for Portland Oregon kosher delis quickly turns up useful hits.

Read this page http://www.kesserisrael.org/kosher.php for an article that
says "The main outlet for Kosher food in Portland is Albertsons Market, located
at 5415 SW Beaverton Hillsdale Highway, corner Shattuck Road, 503-246-1713."

Other info in the article should also be helpful. In addition, you can try
Ron's Center Deli 6651 Southwest Capitol Highway, Portland, OR 97219
(503) 244-0664, which comes up under kosher restaurants. And
Garbonzo's has two locations: 922 NW 21st Ave and 6327 SW Capitol Hwy.

www.kosherzone.com divides the U.S. up into sections and lists kosher markets
in each. In its westzone, they list Albertsons and also Safeway Supermarkets,

6745 S.W. Beaverton-Hillsdale Hwy. (503) 292-5111 and Strohecker's Market,
2855 S.W. Patton Rd., (503) 223-7391

The southwest part of Portland appears to have the concentration of stores.
