Agree with Indiana Jones, Rule #1 when visiting the Disneyland Resort, DO NOT EAT AT Captain Kidd's (located at the Best Western Plus Park Place Inn and Mini Suites on Harbor).
Presuming you are staying with walking distance to the DLR, I like Mimi's Cafe, Panera Bread and The Pizza Press on Harbor.
At the nearby GardenWalk, I like The Cheesecake Factory, Roy's, PF Chang's, CPK, Bubba Gump and Mc Cormick and Schmidt's.
In Downtown Disney I like Wetzel's Pretzels and the Earl of Sandwiches.
And do I need to remind you for Rule #1 again. If you forget rule #1, make sure you know the answer to Rule #2, before your trip, figure out which Hospital and Doctors you can see with your health plan in case of emergency. Yes, it is THAT bad, gets the worst reviews I have even seen for a restaurant on Yelp and other places. If they didn't have a prime location, and an influx of new customers, it would have been out of business years ago. Nobody is a repeat customer.
