For dim sum, there is, oddly, a fantastic, not inexpensive, place in Washington Square mall - Din Tai Fung.
Din Tai Fung is great. It's soup dumplings (Taiwanese), not Dim Sum (Chinese). The pork chop and fried rice is a favorite of mine, as are dumplings with spicy chili sauce. There's a Doughzone (Seattle dumpling spot that people like better than din tai fung) opening at the Riverwalk https://pdx.eater.com/2021/11/16/22786330/dough-zone-portland-dumplings-xiao-long-bao
When I lived in the area we would go to the one on Columbia, in fact went there this past summer when visiting, really good burger that you can make massive and fries. Def a hole in the wall that most people drive right past and never try but worth stopping. In fact I watched the 2007 draft lottery from there and remember telling my dad we were going to be a dynasty .... ughhhhhh.
Doesn't have the condiments that I need. Lots and lots of lemon wedges, fresh ground horseradish, cocktail sauce and tobacco sauce. Then there's the oysters which must be smaller than small, they must be very tiny. There must be no shell grit in the oysters meaning someone experienced must shuck them. The bed of ice shown is also a must. Last, they must be the right kind. I've found Fanny Bay's from Vancouver Island in British Columbia to be reliably delicious. I had one other kind that was even better than the Fanny Bays, a company name, but forgot their name. We enjoyed them at McCormick and Schmidt's in Beaverton (now closed).
If you want great seafood try South Park near the downtown Hilton hotel. We had two dozen shucked oysters without a hit of shell debris. The guy who shucked those really knew his business.
