Many people ask me where to go for beer while they are in Disneyland, since I talk about going there often, so I figure I'd write them all down so I don't have to repeat myself. This is not a complete list by any means, but a compilation of my favorite places (and really the only ones I know of).
Tony's Darts Away
Eagle Rock Brewery
3056 Roswell Street
Eagle Rock is about 40 min from Disneyland, so only go if you have a car (obviously), and plan on spending more than three days at the park, because three days goes by fast at Disneyland.
These guys have a small, unassuming place with no signage that I could see, but inside is a small tasting room with some of the cleanest beers on tap I have ever had. At night there are those trendy "gourmet" roach coaches out front for you to get a tasty meal. Worth the trip if you have the time.
131 1/2 Main Street
Downtown Seal Beach is pretty weird. Blink and you'll miss it. Not just Beachwood, but the whole downtown area. If you do happen to find this place, you will have problems leaving. Not only do they have great food, but a really rad assortment of beer. While you are there, check out the gas system for their draft set-up on the wall. Seal Beach is about 30 min from Disneyland, so again, go if you have time. It's a good place, but not one to miss a bunch of Space Mountain time for. Oh, if you drive by Leisure World, wave to my Grandma! Do it ...
The Bruery Provisions
10 minutes from Disneyland is the greatest deli in the world. Nice big sandwiches served in a small location with a wall of craft beer - refrigerated no less - served by loud Germans. It's hard to get better than this when you are talking delis. And being that it's so close to DL, it's an easy stop. You can buy beers to go as well, which is rad for taking back to the hotel.
