+1 for pok pok, although I like whiskey soda lounge more. Across the street, same owners, similar menu, excellent whiskey and scotch selection, and authentic (i.e. no ketchup) pad Thai.

Regarding the gorge: some hikes are fine on weekends. Eagle Creek Falls trail requires a $5 per car day use fee, which keeps out the crowds. It's one of the best trails in the gorge. Skip it if you don't like heights though, and be careful if it's raining.
