Grilled Shrimp are a pretty good choice!
Keep in mind - there will probably be added oil so you should always round up if you didn't cook it yourself. Even steamed veggies have oil added at restaurants...but you can ask for them plain. Just know they may not REALLY be PLAIN. Enjoy your meal!
And

for researching ahead!!! You won't be going in blind and that's a really good thing.
