I don't find most off-site restaurants all that cheaper or better in general. We would rather stay in the parks (or DTD or DLR hotel) than travel somewhere else. Way too many good choices on DLR property...... including many of the counter service places.
Our experience at Mimi's has been meh.... ok, but nothing to speak of. Def. would not go out of my way to go there or off-site in general.
Except for the fact that the surrounding area is full of "farm-to-table" restaurants. I can order a salad that's made with fresh, local produce that's cut onsite to be served for immediate consumption. Meanwhile, at Disneyland... Disney primarily uses bagged salad that's often comprised of the cheapest produce of the day (whether it's from CA or Mexico) that's often processed in Mexico with added preservatives then shipped back to California, to be served at a higher price point than the local, farm-to-table restaurant (of course, select Disney restaurants offer farm-to-table, but at a much higher price point). Honestly, there's nothing magical about it.
Here are a couple suggestions ->
o Katella Grill offers "farm-to-table," with all food prepared onsite. Their best deals are daily "Blue Plate Specials," in which one entree (rotating based upon the day) is offered at a discounted price. For example, on Saturdays for $14, you get soup or salad, tri tip steak with veggies and gravy, two sides and rice pudding for dessert. Katella Grill offers coupons on Groupon and Restaurant.com, so you can get an even larger discount.
o Farmer Boys is a local, fast casual chain utilizing the "farm-to-table" concept. Meals are around $10, the same price point as McD, Wendy's, BK, etc., but portions are much larger (burgers are 1/2 lb.), meaning you can split. The Entertainment app has a BOGO at most locations.
