Delux Cafe is a South End icon, stewarded these days by husband-and-wife owners who used to be regulars. The popular spot is tucked into a brownstone on the corner of Chandler and Clarendon streets, and the vibe can’t be beat: Year-round string lights and vintage kitsch set the mood in the narrow barroom, which is always packed on a Saturday night. Like other Boston dive bars, the Delux offers a few cheap beers, but it also deals in craft beer and creative cocktails like La Bamba, a spicy tequila sipper with carrot and ginger. The miniscule kitchen dishes up surprisingly great food, such as homemade pasta specials and a Grilled Cheese with tomato jam and crispy shallots. This spot is still cash-only, but the ATM fee is only 99 cents. Never change, Delux.
