An old friend from high school (a looooong time ago) had some extra airline points, so she got R/T tickets from PDX to SFO and came to visit me, after an elapse of a few decades.
After a few days of taking her around to some of my favorite North Bay sights, it was time to relax and take a break. So I asked her if she wanted to go have some dim sum for lunch.
"What's dim sum" she said.
Remember, she's from Portland.
IIRC, Portland has a Chinatown about half a block long.
So, we went to Saigon (Chinese despite the name) in the Richmond/ElCerrito/Albany Asian Mall mash-up area.
We sat, and a cart promptly appeared. Joan was overwhelmed, and started pointing to plate after plate after plate. I had to stop her and let her know there would be more carts coming around.
Anyway, we had a fine lunch, and it only cost us about $20 for the two of us. Now she has something new and exotic to tell her kids and grandkids about.
