100 Montaditos is Madrid's answer to the question "what if a bar served 100 different tiny sandwiches?" — and somehow it works. You order a stack of montaditos (small baguettes topped with everything from jamón ibérico to brie and caramelized onion), grab a cheap caña, and settle in for a casual, no-frills feed. The Palacio location near Calle Mayor and Calle Príncipe puts you right in the thick of the old city, making it a solid pit stop between tapas crawls or a budget-friendly pre-game before a night out.
A hundred mini-sandwiches at €1 each on promo nights — the cheapest, most fun way to eat your way through Spanish flavors in central Madrid.
Go on Wednesday or Sunday evenings for the €1 montadito and €1 beer promo — but arrive before 8pm to grab a table, as it fills up fast.
100 tiny sandwiches, 1 big good time
Look, 100 Montaditos isn't going to blow you away with culinary innovation — but that's not the point. This is a chain that figured out something brilliant: take the Spanish tradition of montaditos (small open-faced sandwiches on mini baguettes), offer a hundred variations, and price them so you can try five or six without wincing. The Palacio-area locations on Calle Príncipe and Calle Mayor are right in the tourist-heavy zone, but they draw plenty of locals too, especially on the nights when montaditos drop to €1 each and beers follow suit.
The menu runs the gamut from jamón serrano and manchego to more creative combos like goat cheese with crispy onion and honey-mustard, or brie with caramelized onion and truffled mayo. Are they all winners? No. Some are a bit dry or rely too heavily on mayo. But at these prices, you just order another one. The olives are genuinely good, and the croquetas hit the spot. Service is fast and the system is efficient — you order at the bar or via a card system, and food comes out quickly.
The space itself is small and functional — a bar, a few tables inside, and some outdoor seating where you can people-watch on the busy street. It gets packed during peak hours and especially on deal nights, so expect noise and a bit of chaos. That's part of the charm. If you want a refined tapas experience, go elsewhere. If you want to spend €10–15, try eight different sandwiches, and have a good time doing it, this is your spot.
