Prague's Czech cuisine has zero spice but immigrants bring the heat. Habesha Ethiopian (Korunní 42, Vinohrady near Náměstí Míru metro) does proper berbere spice blends with real heat. Their doro wat will clear sinuses — Ask for "very spicy" version.

For Vietnamese fire, Pho Vietnam Tuan & Lan (Korunní 96, Vinohrady) makes pho that doesn't mess around. Ask for extra chili oil — They keep the nuclear stuff behind counter for Vietnamese customers, not tourist versions.

Both spots frequented by actual Ethiopians and Vietnamese expats, not Czech food tourists. Cash preferred, Vietnamese phrases help at Pho Tuan.
