A local hookah bar uses HUGE bowls and typically we brings our laptops and a deck of card, plus they have a full menu of food. We spent about 4.5 hours smoking a single bowl of strawberry. I mean seriously these bowl probably carry or 50g's properly packed. Like the KM deep bowl from HC!
The last .5-1hr the shisha wasn't go good, flavor and smoke were pretty thin but we continued on anyway since we had plenty to do
