Tip #1: Eat in Lavapies.
Lavapies, south of Puerta del Sol, is Madrid's multicultural quarter and your halal home base. Moroccan tagines, Pakistani biryani, Lebanese hummus, and shawarma shops line the streets. Meals cost 8 to 12 euros. You can eat here for a week without repeating a restaurant.
Tip #2: Ask "Tiene cerdo?" at every meal.
Jamon iberico hangs from the ceiling of every Spanish bar. Chorizo appears in soups, potato dishes, and scrambled eggs. Even dishes that look vegetarian may use pork stock or lard. "Tiene cerdo?" (Does it have pork?) and "Sin cerdo, por favor" (Without pork, please) are phrases you will use daily.
Tip #3: Master the seafood tapas.
Gambas al ajillo (garlic prawns), pulpo a la gallega (Galician octopus), boquerones en vinagre (anchovies), and calamares fritos (fried squid) are all halal and all excellent. Order three or four plates at a tapas bar in La Latina, share them, and that is dinner for 15 to 20 euros.
Tip #4: Get churros at San Gines.
Chocolateria San Gines has been open since 1894. Fried dough sticks dipped in thick, dark hot chocolate. Completely halal. Open 24 hours. Go at any hour and it will be packed. This is how Madrid operates.
Tip #5: Visit the M-30 Mosque for Jumu'ah.
The Islamic Cultural Centre of Madrid on the M-30 ring road is Spain's largest mosque, with a tall minaret, a large prayer hall, and a cultural centre. Plan for a 20-minute metro ride from the centre. The Madrid Central Mosque in Tetuan is smaller, more community-focused, and historically significant as the first mosque built in Madrid since 1083.
Tip #6: Adjust to Spanish meal times.
Lunch is 2:00 to 4:00 PM. Dinner is 9:00 to 11:00 PM. Restaurants do not open for dinner before 8:30 PM. If you try to eat at 6:00 PM, you will find nothing open except fast food. Adjust your schedule and the city works in your favour.
Tip #7: Day trip to Toledo.
A 30-minute high-speed train from Atocha takes you to Toledo, where the Mosque of Cristo de la Luz, built around 999 AD, still shows its Islamic horseshoe arches. Toledo is where Al-Andalus becomes tangible. For a Muslim traveller, it is essential.
Tip #8: Use smaller musallas in Lavapies.
Several small prayer spaces operate in apartments and storefronts throughout Lavapies, serving the neighbourhood's Muslim community. Ask at halal restaurants or butcher shops for directions to the nearest one. These are more convenient than the M-30 Mosque for daily prayers.
Tip #9: Walk the centre.
The triangle of Puerta del Sol, Plaza Mayor, and the Royal Palace is walkable in 30 minutes. The Prado, Retiro Park, and Lavapies all cluster within easy reach. On a good day, you can cover the major sights entirely on foot.
Tip #10: See the Prado.
The Prado Museum holds one of the greatest art collections in the world. Velazquez, Goya, El Greco, Bosch. Entry is 15 euros, but it is free during the last two hours before closing. Give it at least half a day.
Madrid makes you work for the food, but the art, the tapas, and Toledo give you something back that is hard to find elsewhere.
