I liked these seats because they're angled well and face towards the infield rather than straight ahead. You have to shell out some decent money for section 137, even when the Cubs are down which is most years but it was money well spent.
Just a heads up, the entire day is going to be expensive but you can save money by eating and drinking at 'The Cubby Bear' on Addison before the game. It's all pub food but a lot of the entrees were $7-$10 per item. Plus, it's always packed with the Cubs faithful.
