O' Daugherty's, a great irish pub. It's across the street from the carousel at riverfront park.
Fast Eddies, on the first corner you come to if you cross the bridge going south over the river. Good food, sports bar, great place for a freight dawg to hang out. Kinda divey, though.
Anthony's, a seafood place on the north side of the river, across from the library. Upscale, great view of the river and falls.
