Definitely a restaurant. If I'd cooked it at home I'd know how many calories were in it.
No idea on the Chicken. It was underneath the lettuce and ended up all mixed in. Can't imagine they put much more than 6 oz in though, for $$ reasons. It was on the smaller side of medium for a restaurant salad.
I'll just estimate high and go from there. I'm sure I'll still be way below cal limit for the day (got a little intense working and forgot to eat for much of the day...)
