What dish can you make better than any restaurant?

Title says it all.

Last fall, my GF and I went out every Sunday morning for breakfast at a different restaurant, and I set out to find ONE establishment that could make biscuits and gravy as good as I can. To my severe disappointment, I can't say that I even enjoyed a single restaurant's version of that dish. Almost every single place had gravy that had the consistency of glue and/or was completely flavorless. Keep in mind that we exclusively visited restaurants with good reviews and otherwise good food.

So this led me to wonder what other dishes are much better homemade? Not only is this a curiosity of mine, but I would also love to learn to make more dishes that crush the competition.

Thank you!
