Del Taco is fast food. Its good, if you like fast food..
Everyone hates on their burgers, but they arent that bad. My favorite item however is the shredded beef burrito.. Very tasty.
Chipotle's whole thing is their "food with integrety" meme

I like them ok, but they are kinda pricey for what you get. I mean they roll you a nice hogs leg burrito, but its all rice n beans. If you have them leave the "filling" out, you get a flacid burrito.
Go double meat sure, but then again you are looking at like $10+ with a drink. Got to keep in mind though you are paying for "food with integrety". If you arent into the whole organic thing, and the price premium that goes with it, its probibly not for you.
It also seems to have a starbucks-ey apple yuppie vibe to it which is why I think so many pepople hate it ( other than the food not being to their taste).
Baja fresh made me sick as hell the only time I have ever been there.. They seem to be a common fixture in all the strip malls around here.
