About

L'Ultime Atome is a Belgian brasserie known for its Franco-Belgian fare and distinctive art deco-inspired interior featuring cog artwork. It serves vegan-friendly dishes like vegan burgers and falafel salad alongside meat options, with outdoor terrace seating and accessible facilities. The menu's vegan choices have diminished over recent years, and while some patrons appreciate the lively atmosphere and brunch offerings, others note inconsistent vegan availability and service speed.
