Oktoberfest Brickell, Miami

When the first 100 Montaditos opened in the Spanish seaside town of Islantilla in 2000, the owners had in mind a vision of recreating the classical comfort of old-fashioned Spanish taverns. What they didn't realize was that they were about to start a worldwide phenomenon. Today, more than 300 outposts of 100 Montaditos have opened on three continents, and it's all thanks to their titular menu item—and its 100 variations.

A montadito is a tiny piece of bread, about as long as a finger and as wide as a giant's finger, stuffed with fresh, Spanish-tapas-inspired ingredients. Diners build their meal from a selection of the bite-sized sandwiches off a menu that includes meat-and-cheese combos, all-vegetable nibbles, and even a few dessert sandwiches. Sampler plates let you taste a few popular montaditos in one easy order: the Meat Lover's Collection, for one, includes the chorizo sandwich, the meatballs sandwich with marinara, and four others. Everything goes down all that much smoother with a crisp glass of beer, a Spanish wine, or fresh and fruity white sangria.

The three concepts feature different types of dishes that customers can indulge in:

• 100 Montaditos: montaditos with meat and vegetable options, salad choices, tortilla or croquetas platters; churros or tarta de santiago for dessert
• Cocowhip: coffee, healthy arepas, wraps, toast, pancakes, acai bowls, smoothies, and desserts such as brownie, snickers, pie, or cheesecake
• Kai: build your own or signature bowl salads, tacos, ceviches, sides, such as miso soup
