The cheapest way to experience the club level at a Bulls game is in sections 207-211 on the east side and 224-228 on the west side. While these seats don't offer the same impressive views as seats along the side, they do offer the same amenities at a fraction of the price.
The biggest complaint with club seating along the baseline is that the baskets disrupt too much of the sitelines. This is especially true in sections 209 and 226 which are directly behind the hoop. To alleviate this issue, choose seats off-set from the hoop and closer to the corner of the arena. This will give you a slightly better angle towards the court.
If being behind the basket doesn't bother you, these seats are a great way to take advantage of in-seat wait service and the shorter lines commonly found on the club level.
