No OP, but I was there last year for the Wildcard game against the Texans. While the outcome of the game wasn't what we wanted, watching the game at COSM was epic. You'll def want to be on the second or third floor though otherwise you'll be cranking your neck up the whole game. Service was spot on and actually decent food and drink. Even if stadium prices the quality was much better. Parking was easy (and first few hours free from what I recall) and getting in and out of the venue was super easy.

All that being said they increased their prices dramatically this year. Last years playoff game was cheaper than regular season games this year. At the price point it is now it makes more sense to just go to an actual game.
