Jon,
When was the last time you visited Catalina? Seems like Max has changed his main blend a few more times since the early summer. IIRC he's up to Espresso 2.0, and I think he's offered a couple of others (which I haven't tried). Anyway, the only straight shots I've ever enjoyed at Catalina were pulled by Max himself. I've had shots pulled by a couple of other baristas and not cared for them very much. I tend to get a straight shot whenever Max is in, but I usually come in the late afternoons or on the weekends, so I sadly don't see him often. If he's not in, it's a coin-toss between a cappuccino and a macchiato for me. My test size for bad straight shots is very small, so I'd hold my judgment on that one. I'd give their short milk drinks a good rating, and my test size there is considerably larger, though still rather small--it's hard to motivate myself to go out for coffee in Houston when I can make it myself in my living room, especially since for me the preparation is a big part of the fun!
Even at their worst, Catalina is head and shoulders above probably 99% of shops in Texas. I'd like to hear more of Tyler's experience, and also call you out, man. There's a decent few home-baristas in Houston... you should hang out with us.
Flint, in addition to Jon's invite, you're welcome to come to my place. I live in an apartment near the Galleria at roughly San Felipe and I610, so chances are I'm close if you're in the downtown area (Jon's a much longer drive if that's where you are), and I also usually work from home so I tend to be available during the day. I'm PMing you with my info if you want to come hang out. I've got a small selection of Texas-roasted coffees on tap at the moment. You're welcome to make a habit of coming over during your stay, and naturally you're welcome to make your own. Probably as a couple of weeks pass I'll even have some West Coast coffee for you, if you like!
