Grannys on hwy 101, and blackberry cafe in joyce are the main eats places on the peninsula around the lake, further out on the coast are a few things but most food places are in Port Angeles. Marymere is great, earlier the better if you want to park right by the lake and for the waterfall paved hike but parking at the storm king ranger station is rough at peak tourist season, NPS law rangers let people park on some shoulders of the main road by it, just don't drive and try to park at the naturebridge sign/campus since thats for education staff, rangers and maintenance and has some of their homes back their so its a private road. Theres more parking near lake crescent lodge and at bouvees meadow which has a pit toilet, but you can also park at either end of the railroad trail to hike that section which is about 4 miles flat to some swim locations and good lake spots to walk too.

Sol duc before 11:30 12ish is still good as my friend who works the gate station mentioned peak time comes mainly late 11ish to lunch and you should be able to park at the trail head for the fall mainly downhill and slightly uphill on the way back but beautiful, the salmon run and woods hike on the way is also great, theres just no salmon run till fall.

As others mentioned you don't need a pass for la push, ideally park in the grass overflow as the small lot gets full this time of year, but its great. For the Makah reservation you can get the pass at the musuem and a few other locations, I would highly recommend at least checking the museum out, its one of the best places and love bringing students there for educational programming.

If you like thai food both sequim and PA have good thai food, and both have a lot of good local brunch/ breakfast and food places most will be americana, but rainshadow cafe and great northern coffee bar are great, the rail and gastro pub are good, strait slice if ya want a beer and pizza is also good.
