Things to Do in Istanbul: Itineraries, Costs and Food

Since the 2024 change, foreign visitors use a separate paid entrance and ticket from worshippers. The main floor is an active mosque: it closes to visitors from dawn prayer until 10am for cleaning, and again roughly 12pm-2pm on Fridays for the main weekly prayer. Turkish citizens and Muslim visitors enter free through a different gate.

The Harem is worth the extra ticket, it's where the actual daily life of the palace happened, not just the ceremonial rooms. As of 2023 Topkapi moved from the Ministry of Culture's museum system to the National Palaces Administration, which is why it isn't on the general Museum Pass Istanbul roster except for the main palace grounds; the Harem and Hagia Irene sit outside the pass.

A sixth-century underground reservoir, cool and dim, with the two upside-down Medusa head column bases at the far end being the thing everyone photographs. Go right after Hagia Sophia since they're a five-minute walk apart.

No separate foreign-visitor fee here, unlike Hagia Sophia. Dress code is enforced: covered shoulders and knees for everyone, headscarves for women, and free loaner scarves and wraps are usually available at the entrance if you show up without one.

Reconverted to an active mosque in May 2024 after a long restoration. The Byzantine mosaics and frescoes, some of the best preserved in the world, are covered with curtains during prayer times and uncovered the rest of the day. The Museum Pass is not accepted here. It sits outside the Ministry of Culture's museum system entirely, same as Hagia Sophia, so treat every figure here as needing a fresh check.

Around 4,000 shops under one covered roof since the 1450s. The opening asking price is a starting point, not the price; a counter-offer at 40-50% of the first number and working up is normal practice, not rude.

The Byzantine-era cathedral turned mosque turned museum turned mosque again, its vast dome and remaining Christian mosaics now shared between active daily prayer and tourist visits. Foreign visitors pay a separate entrance fee and use a different entrance from worshippers, with the upper gallery generally the tourist-accessible section. Closed to sightseeing during the five daily prayers, so time your visit and dress modestly, headscarves required for women.

A 17th-century imperial mosque facing Hagia Sophia across Sultanahmet Square, named for the blue Iznik tiles lining its interior, still an active place of worship. Free to enter outside prayer times, one of the few major Istanbul sights that hasn't started charging tourists. Closed to visitors during prayer, and there's usually a queue at the main tourist entrance regardless of time of day.

One of the world's oldest and largest covered markets, thousands of stalls across a maze of vaulted lanes selling carpets, ceramics, jewelry and leather. Worth seeing once for the scale and architecture, but treat it as a tourist trap on pricing, everything is marked up and haggling is expected and necessary. Buy nothing at the first quoted price.

Public commuter ferries and dedicated sightseeing boats crossing between Europe and Asia, passing Ottoman waterfront mansions, fortresses and the two continents' bridges. Skip the touristy full-day cruise packages, a regular public ferry between Eminonu and Kadikoy or Uskudar gives you the same skyline for a fraction of the price. Genuinely one of the best ways to see the city.

A hillside district of colorful old houses along the Golden Horn, once a historic Jewish and Greek quarter, now full of vintage shops, cafes and murals that have made it a social-media staple. The colored houses are real but it's become heavily gentrified and staged for photos, expect a queue of people waiting to shoot the same three streets. Wander further into the surrounding lanes for the version that's less performed.

A 6th-century underground water reservoir beneath the old city, hundreds of columns rising from shallow water, two of them resting on carved Medusa-head bases. Genuinely atmospheric and well lit, one of Istanbul's better indoor options in bad weather. Book a timed ticket online, walk-up lines at the entrance can be long in peak season.

A spread of cheeses, olives, eggs, honey, jam and bread rather than a single dish, meant to be eaten slowly over an hour or two, not on the way somewhere.

Hand-minced lamb packed with fat and chili, grilled on a wide skewer over charcoal. Order it with grilled tomato, onion salad and lavash, and expect real heat.

Made from the same hand-minced lamb as Adana but without the chili, darker and smokier from a heavier char. Order both side by side to feel the difference.

Thin-sliced doner laid over pide, doused in tomato sauce, browned butter and yogurt. Rich enough to be a full meal, and different enough from street doner to earn its own name.

Sliced to order into bread or a wrap, meant to be cheap and fast rather than a sit-down meal. Quality tracks turnover, a busy spit beats an elaborate menu.

Small cold and hot plates shared across the table, paired with the aniseed spirit rakı cut with water. A meal here runs long by design, not by accident.

Thick, unfiltered and served in a small cup with the grounds settled at the bottom. Order it az şekerli, a little sugar, unless you actually want it bitter or sweet.

The actual daily habit, served in small tulip glasses, strong and usually with sugar cubes rather than milk. Free or near-free at most small shops as a courtesy.

Gaziantep sets the benchmark, thin layers, real pistachio, not overly sweet, and Istanbul shops that trade on that reputation are worth seeking out over the tourist-strip boxes.

Grilled mackerel in bread with onion and lettuce, sold from boats by the water. It has become a tourist ritual as much as a local lunch, decent but not the city's best food.

Thick milk chocolate bars filled with pistachio cream and crisp kadayıf, the viral Dubai dessert now stocked in Istanbul patisseries and supermarkets. An import craze, not a Turkish dish. Fun to try once, but real baklava from a Gaziantep-style shop is the better use of your money.

A cluster of third-wave roasters and cafes in Karaköy serving pour-over and flat whites alongside the usual Turkish coffee and çay. Genuinely good coffee and worth a stop, though it is aimed more at Istanbul's own young professionals than at a specific tourist trail.

Michelin expanded its Turkey guide nationwide for 2026, pushing the country's starred restaurant count to 17. Istanbul is now part of a much bigger national map instead of standing alone. This is a credibility signal more than a single spot to send readers to. Frame it as context for the city's fine dining, not a discovery.

Annual food festival held at Tuyap Fair and Congress Center returns each autumn, bringing chefs, producers, and food brands together. Good for a plan-your-trip-around-this angle if dates line up, but it's a trade-style festival, not a foodie photo-op.

Istanbul's meyhane scene is being reworked by younger chefs and owners, keeping the raki-and-meze format but updating the plating and wine lists. Cover this as a category, not one named place. Several guides are tracking it as an ongoing shift, not a single opening.

Istanbul landed at 24th on TasteAtlas's 2026 global food city ranking, with Gaziantep at 17th in the same list of Turkish cities. It's a ranking mention, not a hidden find. Use it as a supporting credibility line rather than the whole pitch.
