The Scheldt, definitely not. Splendid isolation (and HUGE rabbits).
From the Amsterdam Aire to the NDSM wharf (where the free foot ferry leaves from) there are several restaurants.

The Nooderlicht is a funky cafe smothered in found objects and quirky metallic scultures. Pllek looks fairly posh, and you probably need to book. There's a cafe / bakery called 'Brood' right opposite the ferry stage, where everyone hangs out waiting for the next ferry then, just past that there is a nice looking place called De LJ-Kantine. I've a feeling the Double Tree Hilton hotel has a restaurant, though I can't be certain.
I stayed at the Aire for a couple of nights between Christmas and New year last year, and I *think* they were all open, though I didn't eat at any of them. It was bitterly cold & foggy. The foot ferry passes a derelict Soviet-era Zulu class submarine (B-80), plus the Veronica (sister ship to the Caroline of radio fame) is moored there.
Although it's not cheap (€20, €26 incl EHU), it makes visiting Amsterdam a doddle, and I wouldn't hesitate to go back there again.
Morph.
