Attention NYC OOTers: Need some quick Shea Stadium advice

[Slow Play Ray]

Hopefully someone can answer quickly before my buddy orders tickets...

We are going to NYC this weekend to see Dispatch, and we decided to take in a Mets game Sunday afternoon. We are of course Red Sox fans so only plan to buy $20 tickets to get in the stadium, my question is what are the best $20 seats, or do they all suck and we should upgrade to some $31s:

UPPER RESERVED $20
LOGE RES BACK ROWS $20
MEZZ RES BACK ROWS $20
UP RES NO ALCOHOL $20 (clearly not an option)
MEZZANINE RESERVED $31
UPPER BOX $31

Thanks in advance...
