Sat here earlier this season while the Brewers were in town. I love divisional games; they're always must wins for the Cardinals. The seating is a little cramped in some areas of the ballpark and roomy in others. I've sat almost everywhere but the bleachers and refuse to ever sit there.
Section 267 has a laid back vibe to it as do most of the "Loge" seats. The fans in 267 were great and I loved sitting in a small section with only 13 rows of seats. Each row had maybe 10-12 seats to a row so we had extra quick access to leave and hit the concourse.
These seats are NOT sold as season tickets which is great, we were able to purchase them from the Cardinals box office in advance. I highly encourage other fans to do the same rather than buying from a scalper or online ticket broker like stubhub.
Our view of the outfield was definitely better than our view of the infield but that's a given based on our location towards the left field corner. The seats on our same level was part of the "Redbird Club" and those tickets took a considerable hike in price. Take my word for it...not worth the money. The view here is almost just as good and feels just as close to the playing field.

A few other tidbits:
-The main team store is near Gate 3.
-Tours are $10 but you need to book in advance as they only book on certain days.
-Kids under the age of 3 are admitted into the stadium for free.
