Ree, are we on a first name basis, can I call you Ree? Which do you think is more informal, P-dub, or Ree? When are we going to do lunch? Do you have any trips to California planned?
OK- your counters- this is what you said:
The kitchen cabinets are in, and Terry and Jerry have put plywood countertops on
them to give us an idea of how they’ll look. We’re still making final decisions
about countertop materials, and since we have a lot of countertop area to cover,
we’re looking for ones that won’t be prohibitively expensive. I’m thinking of
concrete (no color; just naked [but sealed]), butcher’s block, and/or marble,
but not fancy schmancy marble. And maybe galvanized steel. Don’t laugh; we have
it at our farm, and it’s cheap and rather charming.
What counter top
materials am I missing? What’s cool and hip and not typical
My advice?
- Concrete is not terribly inexpensive, averaging over $100/ square foot where I live. Unless, perhaps, you have a special source. Great look- I would love it in your place.
- Butcher block- No- too much "wood."
- Marble... I love the look of marble. At the firm that I worked for down in LA- we were not ALLOWED to use marble in the kitchen because it is too porous. So- great look- LOVE the look- but beware- it would be a shame if it were to stain. I would love a honed limestone... But again- not the most practical of surfaces.
- Galvanized steel? Interesting. I have not seen it done- but it sounds cool.
My suggestions:

1. I liked your concrete idea- it is a great look.
2. Slate: Used for centuries to create stylish weather resistant roofs, slate's natural beauty and strength are finding their way into the kitchen. Befitting of a roofing material, slate is durable, hard and fireproof. Luckily, it's beautiful, too, making it a prime choice for homeowners seeking a counter top that will make a statement. Its low absorption rate keeps stains at bay, though you may want to seal regularly to add a further dose of protection.

Soapstone: (picture above) Often referred to as "the original stone counter top," early settlers in New England relied on the durable material for their own counter tops. Far from a high-maintenance top, soapstone's inert nature means acids won't etch the material, and stains can be rubbed out. Mineral oil treatment will bring out a darker, richer color. Make a powerful statement by combining with a soapstone sink.
Quick tip: As you investigate your natural stone options, consider functionality first, then this: do you want a stone that will look brand new 10 years from now, or one that will take on the patina of age? Let your answer help guide your choice.
To clean: Stone is a natural product, and cleaning is fairly simple, though be sure to follow specific instructions for your stone. Monticello Granite, the first nationally available counter top company, recommends that stone surfaces be cleaned with a few drops of a neutral cleaner, stone soap or mild liquid dish washing detergent. Always avoid products containing abrasives, lemon, vinegar or other acids, as well as scouring pads. 
Also- consider re-cycled glass- Made of 85% recycled glass- this is "in" because it is "earth-friendly" :). This is also more of an option for a place like P Dub's- because it lends itself to be that juxtaposition of shininess in a rustic interior, whereas true glass is just too modern.

Paper-base- Say sayonara to stone. Richlite’s paper-based countertops provide a durable-as-stone and heat and stain-resistant surface that's more than just a unique countertop alternative. Used in commercial kitchens for years, Richlite is available in six colors including sage, slate black and nutmeg. Using only sustainable materials, Richlite is the first company to offer hemp-based countertops, which are both heat and stain-resistant. Cost: $65-$75.
Personally, I think in a kitchen like the one you are doing, I would do a counter that is not the focal point- something with a dull surface- a simple color- The focal point of the kitchen should be the hood... which I will discuss next time :)
So- anyway... call me :)- we'll do lunch!
