Give it another shot.I was disappointed with Chipotle the one time I tried it, but then again I'm fortunate that I live in an area where I can be extremely picky and snobby about what my tortilla gets wrapped around.
I plan to, but I'll probably wait until I'm out on the road somewhere away from my favorite taquerias and needing some beans and rice and meat. My main complaint is that the flavors didn't blend well, the rice didn't complement the meat or the beans and each component was sorta bland on its own. That and the steak was kinda dry, which is a bummer because the chunks were really huge.
One caveat of burrito critique is that I've had a bad burrito in almost every one of my favorite burrito joints. A burrito is a delicate ballet, and sometimes one ingredient sits in the steam tray a little too long, so unless I get something really horrible or gastroenteritis I'm usually willing to give a place a second chance.
Is Sonic really all that? I'm exposed to approximately 7 to 8 Sonic ads an hour during the NBA finals, but the closest Sonic to the Bay Area is in Tracy so I'm not likely to casually drop in and I never tried it when I lived in San Diego (that seemed to be more of a Ralley's town).
