If you're looking for a classic Puerto Rican eating experience, get back to the basics with a cup of coffee and breakfast in this cozy, timeless nook on San Francisco. Cheap and simple, the Mallorca is where all-night ravers share pick-me-ups and American journalists sift through their travel notes. No frills, but plenty of warm familiarity.

The place is known for its namesake specialty – the classic, sweet and soft mallorca. A traditional bun served with sugar on top, you can have yours sweet with jam or savory with a choice of meats and cheeses. Try the ham and Swiss cheese, lightly toasted. You'll get a hot treat that's thin, slightly crispy and oozing with salty, cheesy goodness. The dash of powdered sugar adds an unexpected – and surprisingly good – kick.

For the best experience, sit at the bustling counter where the veteran waitstaff keep you plied with cafe con leche while you watch the mallorcas being prepared by the dozen. The rest of the menu features traditional Puerto Rican fare and simple sandwiches. Service is speedy.
