It may be a comparitive bargain but that still doesn't mean it's affordable for a family of 4 with a normal income. I've never spent $150 for 4 dinners in my life... I've never spent half of that, and I'm not sure what you're buying at Wendy's, but I can assure you my wife and I can eat for less than $20.
If I lived in the area, I'd be ok with spending $80 for my wife and I to go to this game. I would not be throwing another $80 away on the 5 and 6 year olds who couldn't care less. They'd stay home with family.
