Obeying the burgermeisters' commandments of an ideal meat-to-bun ratio, non-greasy savouriness, significant side spillage and meat seared to a good char, the Lounge is bound to outlive the haute burger trend. An open kitchen contributes to the raucousness, with customers ordering at the register, and burgers grilled in eyeshot, swaddled in paper, and then delivered tableside. La Madre buns are the burger-bearers, and the menu includes 10 organic beef options and such toppings as caramelised pineapple and jalapenos. There are also lamb choices, unground fish and chicken varieties, and vegetarian knockouts.
