I propose a second way to buy the Special Drink in the Tavern. Completely separate from the 1 h cooldown option for 5 coins, we should have an alternative option to be able to buy the Special Drink for 100 Lounge Chips. This option would not have a cooldown and would be unlimited, but I think it would be balanced because of the high price to pay for it.
This would solve the Lounge Chips accumulation problem and would give players with big amounts of Chips an option to use them for some progression.
