Since the last post with Crescent City in the title is over two years old, I thought I'd post a separate update note.
We spent a few nights up here vacationing from the Bay Area and now understand why Crescent City doesn't get much discussion in Chowhound :-). Thanks so much to the people who posted about Good Harvest Cafe. Both breakfasts and lunches are wonderful here and we ate there every day.
For dinner things get trickier. The Beachcomber has pretty good grilled fish specials, but the sides aren't as good as the fish. The only other place we found that we could recommend is the Circle J Pub on 101, between Beachcomber and downtown. The menu is pizza, sandwiches, and salads. The Caesar salad is really good. The pizza isn't the best we've had, but made from good ingredients, though a bit underseasoned.
