I have found that for my crew one of the things that keeps us out of resturants is figuring out a few ethnic take out type dinners to make at home. We like Thai so figuring out a decent pho and pad thai has been helpful. Friday night fish fry is a big regional food here so we have the coleslaw, homemade oven fries, and storebought fish fillet to tame the cravings. I still think that a slightly less than healthy semi-homemade dinner is still better both nutritionally and dollarwise than a full blown meal out. Personally I have given up on homemade sushi though.
I attempt to make a lot of ethnic foods sure it might not taste as great BUT it is cheaper...and I also don't attempt Japanese night anymore...(occasionally make maki rolls for lunch/parties) but for 11.99 each dh and I can go out for all you can eat veg sushi for lunch(they never charge us for dc ) and get WAY more selection/side dishes then I have time to make and those days I don't have to make dinner we're so full
