jcg-
We were concerned about Bottega as well, but the consistency problems went away, and they've been serving top notch grub for at least 8 months-- whether Chef Chiarello is there, or not. Five of us dined there a month or so ago, and actually had to re-order a few dishes, because we loved them so much we had to have *more*! (can't think of the last time this happened). It wasn't that the servings were small (they weren't)-- we ordered shared appetizers (calamari, and another dish-- slips our minds)-- both were so outstanding that the plates were clean within minutes.
The rest of the meal (entrees especially) was also outstanding.
We would have sent you to Morimoto, since only about 30% of their menu is sushi-- the rest is what we'd call "Iron Chef"-- incredibly creative and wonderful tastes/flavors. But mini has a point-- if there are some in your party who object/don't care for asian spices, then Morimoto may not be the right fit.
Here's a review of Morimoto-- remember that they can do their Omakase (taster's menu) to be completely sushi-free, if needed:

We think you're smart to forgo steaks-- Coles Chop House has GREAT steaks/chops, but Houston has its own great steak houses, too!
We also love Bistro Jeanty, if you're looking for a country French style Bistro. Great food, and wonderful ambiance.
You don't mention when you'll be here. If you need/want a Thomas Keller fix, the only place of his open between now and March 1 will be Bouchon. We're hoping Bouchon Bakery opens shortly thereafter-- the locals are starting to go through withdrawal! :)
BTW, you will find so-so reviews for both restaurants and lodging properties in the Napa Valley. That is, in part, b/c prices are high, and folks go in with extremely high expectations. Sometimes those expectations are not met (= mediocre review). Bottega *did* have consistency issue w/its service and food quality, but we have not personally heard of any problems for months and months (we have had close to 100 of our guests go there during this time, and they've all raved).
Hoping this helps!
