Isla de Café (CLOSED)

From a gleaming vintage Airstream parked inside Humboldt Park, Cristina Ayala and her smiley staff are pressing Latin-inspired sandwiches to order and pulling potent shots of espresso for straight-up eye openers or iced concoctions. Muenster melts into ham between eggy, sugar-dusted bread for the malloraca, while a pastrami sandwich is done as it is on modern food trucks in Puerto Rico: piled high with grilled onions, white cheese and mustard then toasted. Everything is as cheap as it is tasty, especially the Puerto Rican pastries sourced from the best bakers around.
