Being currently stuck in Duluth I'll comment for what its worth.
Food:
Sir Bens has good sandwiches and nifty import beers. Sometimes live music and in general a bit of a lefty/hippie deal going on with the patrons. I like to get sandwiches there, although they aren't as good as they used to be.
Pickwick: Probably the best, quality wise, restaurant in town. Its close to Sir Bens.
Radisson: Yeah it spins around. The food can be good or bad, service is usually worthless for the most part.
Portland Malte Shop: Great malts, probably some of the best anywhere. Also closed right now. Bad luck.
Pizza Luce: Strange pizza abounds. If you are into that, its not a bad place.
Sights
Hawks Ridge: Just a mile or so from where I'm at right now you can drive to the lower overlook, but the upper overlook is closed to traffic so you'll have to hike it out, but its not that far.
Brighton Beach: Usually home to piles and piles of ice now, but its not cold enough so you can still get down and see some waves without leaving your car.
Canal Park/Lakewalk area: Probably a bit cold, but you can get right down by the lake.
Bars & Stuff
College bars: Grandmas (formerly Grandmas Sports Garden), Duluth Athletic Club, 21 North
Normal Bars: Dublins, Sir Bens, Grandma's Saloon, Brewhouse
Not worthwhile strip clubs: Saratoga, Fuzzys, Pink Palace (I think it has a new name)
Worthwhile strip clubs: (none)
