More NYC travel advice, please

I'll add my two cents:

I am not the person to ask about crabs or the Harlem restaurants. Or Chinatown for that matter... So I'll defer to others.

But, yes on walking the Brooklyn Bridge. I do it often and I find it therapeutic sometimes. It's just beautiful, especially at night. Only bad thing is that over the last 15 years it has become a more popular thing to do, so you get tourists walking slowly or stopping to take photos and it can be really slow getting across -- the pedestrian lanes aren't made for more than 1 1/2 people going each way, so it just takes one idiot to create a backlog.

When you get to the Brooklyn side, go for Juliana's over Grimaldi's. Depending on when you go, there will likely be lines at each. It's a bit of an involved story, but the original Grimaldi family sold the place (guessing about 30 years ago). It remained really good -- owned by Russians, I think. About 5 years ago, though, they were losing their lease and they ended up moving a few doors down to the corner of Front Street -- bigger restaurant. That is when the original Grimaldis moved back into the original restaurant (with the coal oven) and opened Juliana's (they don't own the rights to the Grimaldi name anymore). They are both good pizzas, but Juliana's is the better of the two -- depending on how you want to argue it, Juliana's might be the best neopolitan pizza in the city.

On Arthur Avenue, yes -- do it over Little Italy; it's just a trip if you aren't going to be up there for something else. A bunch of good restaurant choices, but I like Dominick's -- really good, old school Italian food.
