For a fine-dining burger to be a must-order, it’s gotta bring something special. This lunchtime-only burger ($14) does just that: It takes the restaurant’s beloved bacon-wrapped, chorizo-stuffed dates as inspiration for a beef-chorizo patty slathered in date mostarda and piquillo aïoli and crisscrossed with strips of crisp bacon. That special enough?
