Eating out can be difficult since most nutrition information is not provided. The American Diabetes Association gives great tips such as: Table Tips, Dining on Time, The Fast-food Challenge, and what to order when dining out.
Personally I like eating at home and making my meals, but sometime I can't avoid it, so it's helpful to know what to order.
