I haven't been in the coffee game for almost 8 years, but I think the Gibraltar is 4oz or something. When I worked at Victrola, we'd have people come in from your area semi regularly. They held cuppings there, too.
As for the vinyl bars, I have a friend who does regular DJ nights at Revolver and I have a friend who works there, but I've never made it in. I don't make it out that way as much and I have a kid, but I should make the effort. Just based on who those two people are, alone, I'd say it's worth it.
Life On Mars just opened and I know the owner Steven. He also owns Neumos. I haven't been in there yet, either, but it literally just opened. The co-owner is John Richards from KEXP. John always seemed like the more senior DJ at the station and handles other positions there, as well, but he's not really my favorite, as far as his musical tastes. Steven is really excited about the venture, though, and he's always been really cool to me. It's definitely something that they believe it. If you have the time, I'd probably check it out. I'm planning to do it, when I have some time, myself.
You'll be here in two weeks, eh? I couldn't remember when you said you'd be out this way. Bill Callahan is this Saturday, but I'm sure something else will be happening in town when you come through.
