As indicated in my post I think the key factors are the location of your gate and time you plan to spend on the lounge and what you want to eat. If you have at least an hour in the lounge then Clubhouse may be worth the walk. Just anticipate a looong walk to/from lounge if your flight departs from the B30s or higher. Otherwise the Amex lounge is one of the better ones and drink service is instantaneous.
