I don't know if this place is open anymore - I hope so. Nice place to stop in for a beer and sandwich and it's right on the river, a short walk from the flats and not too far from the warehouse district. You can usually park across the street under the viaduct.
This is basically just a local bar so don't expect fancy. The food is good and they have many beers on tap - especially Guinness. Gets a good crowd on game days (Football, Baseball, Basketball - take your pick). shuttle service to Jacobs Field.
Go during the day and take a short walk to see the swing bridge - a really neat engineering marvel. Get lucky and watch a freighter make it's way up the Cuyahoga - they don't call it the crooked river for nothing.
