A Hollywood set designer couldn’t imagine a more “typical” Spanish bar, from the dark wood and florid 19th-century tiles to the dim lighting and the barrel of manzanilla sold at a pittance per glass. The perfect complement to that mild sherry is an inexpensive plate of sheep’s milk cheese with membrillo (quince paste). For a meal, it’s hard to beat the ratatouille with fried egg. For authenticity’s sake, do your eating and drinking while standing.
