Işkembe çorbası (tripe soup) is made by slow-simmering cleaned beef tripe until it becomes tender, then thickening the broth with a mixture of flour, butter, and buffalo yogurt that creates a silky, creamy texture. Paçacı Mahmut Usta's version is particularly renowned — Turkish food guides cite it as among the finest in Istanbul. The soup is served hot in a deep bowl, sometimes with a raw egg yolk and lemon juice on the side (called 'terbiye') that the diner can add for extra richness and acidity. The tripe itself is soft and gelatinous when cooked properly, adding body to the broth without any gaminess.
Tips from diners
Try işkembe with terbiye — ask the server to add an egg yolk and lemon juice to your bowl. This traditional preparation adds richness and brightness that transforms the soup. Don't be intimidated by the tripe; cooked properly, it's tender and mild.
This soup is legendary as a post-drinking stabilizer. Locals swear by it on New Year's Eve. If you're going to try it, order a bowl, eat slowly, and let it settle in your stomach for 10 minutes. The richness and warmth work on a physical level.
Paça çorbası is made by boiling lamb trotters (feet) and sometimes head meat until they become very tender and start to fall apart. The resulting broth is finished with yogurt and butter, creating a creamy texture. The trotter meat adds collagen that gives the soup body and a silky mouthfeel. This soup is equally famous as işkembe and serves the same cultural purpose — it's a traditional New Year's Eve soup served right after midnight. At Paçacı Mahmut Usta, it's made fresh each morning.
Tips from diners
Order paça çorbası if you want a soup that's richer and more substantial than işkembe. The meat in the broth makes it more of a meal. Both are worth trying if you visit twice.
The restaurant doesn't have a pastry kitchen — bread is sourced from a local bakery. It's simple, warm white bread that's perfect for tearing and dunking into the soup, which is the traditional way to eat paçacı soups.
Tips from diners
Ask for bread. Tearing off pieces and dunking them into your soup is the traditional way to eat this. The bread soaks up the broth and becomes soft and savory.
A variation on the soup theme, this dish features tripe braised with chickpeas until both are extremely tender. The sauce is savory and slightly spiced, coating each piece of tripe and chickpea. This is a heartier preparation than the soup and works as a main course rather than an appetizer or hangover remedy. It's less famous than the soups but equally delicious and available daily.
Tips from diners
If you're visiting for lunch and want to eat rather than drink soup, order tripe with chickpeas. It's solid, sustaining, and the chickpea adds texture that the soup versions don't have.
A combination of both trotter and head meat in a single soup, this dish includes the tender, gelatinous meat from both parts simmered until it falls apart. The collagen from both sources creates an remarkably silky broth. This is the richest and most substantial soup on the menu, and it's what Turkish families traditionally serve on New Year's Eve after midnight.
Tips from diners
This is the most traditional of all paçacı soups. If you want the authentic New Year's Eve experience, order the head and trotter combination. It's the richest and most traditional version.
Paçacı Mahmut Usta has operated since 1978 in the Kıztaşı area of Fatih, specializing in offal soups and traditional Turkish tripe dishes. The founder, Mahmut Usta, came from Erzurum and worked as a chef at the famous Hünkar Restaurant before opening this modest neighborhood spot. The restaurant serves işkembe çorbası (tripe soup) and paça çorbası (lamb trotter soup) made with buffalo yogurt, butter, and flour, creating a creamy, savory broth that's simultaneously satisfying and light. These soups have been a Turkish New Year's Eve tradition for over a century—served right after midnight as the supposed hangover cure. Modern usage still follows this pattern: the restaurant opens early morning and serves a late-night crowd of revelers seeking to stabilize after a night of rakı. The menu is minimal and focused; if it's not tripe or a sheep organ, you won't find it here.
This is a no-frills, utilitarian restaurant. There's no wine, no beer, no menu beyond the soups and a few stews. The decor is basic. You're here for the soup, not the atmosphere. Go, eat, and leave.
The restaurant opens at 5 AM. It's busiest in the early morning (5-7 AM) when construction workers grab soup before work, and again at evening (6-8 PM) before closing. Midday is quieter.
Don't overthink the choice — both işkembe and paça soups are famous and good. Most diners order one or the other. If you're unsure, ask your server which was made freshest that morning and go with their recommendation.
