Casa Mia, without a doubt. I always go there. I also had a fairly good experience at the new Anthony's, Hearthfire Grill. The appetizer was good. My White Russian was good. Sadly, the main course was only mediocre.
If you search "Olympia" on this board, you will find lots of suggestions. Perhaps you could be more specific in your request ---- are you looking for ethnic, seafood, high-end, low-end, waterfront, BBQ, etc., etc?
