Quick review of Comerica:
Really nice ballpark. Great sight lines, fairly close to the action. Minimal food options* in the ballpark proper, just endless repeats of the same few options, all blocking views from the concourses. Tough getting there, and leaving, but great built up area around the park for before/after.
*Two really neat areas inside the park: a huge outdoor picnic area with a kid's ferris wheel behind HP with an actual working open pit BBQ that upgrades the food options by a million percent. There's also a kind of food court area with multiple good options and a merry go round.
Best feature: the absute best seating I've ever seen, these are the last 10 rows or so of the lower bowl from 1st to 3rd. Spacious, comfy, table for every 2 seats, waiter service. Dunno what they cost, but from what I hear you can sneak into 1 by the 3rd inning or so.
