They don't have nearly the same demand for dining reservations at Disneyland as WDW does. There is no +10 policy that I am aware of if you are staying at one of their three Disney hotels.
Last year when we went, it was 60 days out for making priority seating reservations. According to AllEars, "you can make your Priority Seating for all Disney and Downtown Disney restaurants EXCEPT Rainforest Cafe by calling 714-781-DINE (3463) up to 60 days in advance." You'll also find updated menus to all Disneyland restaurants on AllEars.

If you're interested in dining at the Blue Bayou, those reservations go quickly and I recommend getting those well in advance. Other popular ones include Goofy's Kitchen at the Disneyland Hotel, and Minnie's character breakfast at the Plaza Inn. The Carnation Cafe has very limited seating, and reservations would help save you a lot of time there. Here's a neat website on dining at Disneyland.

I really enjoyed the Storyteller's Cafe at the Grand Californian, and the Wine Country Trattoria at DCA. Both were outstanding. The Carnation Cafe right on Main Street has a very unique ambience too for dining. It's so magical to be served outside there especially during parades.
There is also a dessert buffet for Fantasmic that takes reservations 30 days out. These reservations go very quickly since seating is very limited. It's neat to do once if you haven't done it before. You have the option of seating from a balcony in New Orleans Square or a roped off area up close to the show.
I had so much fun at Disneyland for the very first time last year that I'm returning this summer. The level of magic just overwhelmed me everywhere.
