There's a few foods I won't eat at restaurants; meatloaf, spaghetti, and most alfredo's. Mainly because they're straight from the can, or they use ketchup to base the meatloaf, which I can't stand.
I have been pleasantly surprised by Roma's despite them having Mexican's making the food. The family that owns it is from Italy, so I imagine their recipes are being used to cook with, and not cans of crushed tomatoes. The Alla Panna sauce is fucking amazing.
