i always get the mixed grill now that i am watching what I eat (a little)
it has chicken and steak with veggies and some awesome potatoes
the first problem with olive garden is the wine
then the oily rolls
then the oily salad
then the calorie laden alfraedo sauce
then the serings
they probably serve you 5 servings of pasta in one dish. They do not publish their calorie counts that i know of, and that is always a red flag for me.
Having said that, ANYTHING can be eaten in moderation and I am sure you can squeeze in a good meal here and there (this is from me, I am loosing 2 lbs a month), you would have to ask someone loosing 10 lbs a month, I bet you they are not going to olive garden.
