The best bang for your buck probably lies in sections 509 to 517, where seats can be had fairly reasonably had for any game that isn't Opening Day or the Subway Series – and the entire view of the field is unobscured. If you're thinking nearly anything beyond the infield of the Promenade section will run the risk of some of the playing area being unviewable. In addition, the seats are right above a large food court that sits behind home plate in the upper deck meaning the walk to get any substantial food is quick and easy, as well as a wider variety of beers than one might get from a vendor at their seats. That food court also features a box office for future ticket dates, which almost never features any wait. If you're planning on buying tickets to future games at the box office outside the stadium, wait until you're inside and head to the upper deck food court. On value dates, sitting in the upper deck, or "Promenade Reserved” is $12 once you get out near the foul poles, with the costs getting up to $20 or $50 for the more desirable games. Beware the low rows in the promenade once you're past first or third base. The clear plastic walls around the section stairwells could obscure most of the infield and the outfield corners will be cut off. Avoid low rows in the Promenade reserved (501 – 504, 524-528)
