You might have to ask for "no added fat." I'm sure most restaurants would slather them with butter before or after they go under the broiler. Scallops by themselves are low in fat and high in protein, so I'd say they'd be a good choice.
it says served with lemon and butter so i am going to ask for no butter and hopefully they can do that..im going to out to eat @5:30 and really wanna make a smart choice
