you need something fat to cook all that fish fish and meat... maybe olive oil.
... go to the grocery store and slowly do the alleys, buy what you like to eat and bring then with you.
I didn't think of those things, and surgar, etc because I live aboard and so they are already on my boat :-) Already have two large bottles of olive oil and more vegitable oil than I eat in months (1 large bottle).
I'm not much for munching, so I went light on munchies. Mostly, beef jerky and tortilla chips.
As for the coffee in ballard, ballard is right across the channel - so I'll get in my skiff and row over there right now! But, I always thought the best coffee Seattle had to offer was Vivace.
