Most restaurants close early but Jewish Quarter ruin bars don't sleep. Frici Papa open until midnight weekends - perfect post-Instant Hungarian comfort food.

24-hour options: McDonald's at Deák Ferenc tér metro hub, Govinda gyros near Kazinczy utca party district until 4am. Not glamorous but hits spot after ruin bar crawls.

Classier late night: Spíler Shanghai in Buda serves Asian fusion until 1am. Kitchen actually stays open past Szimpla crowds, not just pálinka shots.

Night markets aren't Hungarian culture, but 24-hour CBA convenience stores near Váci utca sell decent lángos sandwiches.
