With such a name, we hoped this place wasn't going to do exactly as it says on the tin. But thankfully, the hot air is not bravado, but an allusion to old Zepellins flying around the skies, and the imagery of coffee machines at work, producing steam. That's why you're here, right? Other than being drawn to the painted murals inside by Cyprian Łukasik, the immediate reaction to this place is the brow raising size - quite big for a cafe. That's the great thing about it, for there are only a few tables, all spaced out nicely to allow you and your friends to talk in a relaxing environment, not squashed up amongst 20 tables for maximum 'cost effectiveness'. The interior is sparse, with plain wooden shelving and basic lighting, all set amongst some chill music, but trust us, it's something you'll like if it's a calm place you seek. Oh, and the teas, coffees and sweet treats are damn good too.
