Perhaps the grand irony of this operation is that the delightfully-fluffy sweet and phenominally-decorated cake products that come out of this kitchen are the work of heavily-tattooed death metal fans (hence the name 'Hardcore Muffins' we suppose!). This vegan/vegetarian cafe is extremely good at what they do, which is making food (not just cakes) with certified eco products that are made on-site. They serve breakfast all day (think shakshuka, scrambled eggs, tofucznica, vegan English breakfast, pancakes, bagels) which you will pay a maximum of 25zł for. Coffee is also available, including funky new methods of drip, chemex and aeropress.
