This Mo's restaurant was located near the Yakima Bay in Newport. It was very small compared to the other ones we have dined at. There must have been no more than a dozen tables. It was located across the street from the pier area, so there was no water view. Mo's is supposed to have excellent clam chowder. I'm not a real chowder fan, but the people seated next to us had a huge pot of chowder and a basket of bread brought to their table. We ordered the Halibut Fish and Chips. It was good and reasonably priced. I think it was $11 or so. My kids ordered chicken fingers from the children's menu. They were deep fried, dinosaur shaped. We buy the same ones at Costco, so my kids weren't really impressed. The kid's meal didn't come with a drink and was 4ish.
I would recommend driving over to Lincoln City to the other Mo's. It overlooks the water and is larger.
