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?
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.
