Polished service and upscale yet unpretentious dishes, like beef-tenderloin pizza topped with mashed potatoes and white-truffle oil, make Mistral a perennial South End hot spot. Grab a table by the arched, floor-to-ceiling windows or a seat at the always-buzzing bar—either way, there'll be plenty to see in this airy white room with a Provençal-theme decor. Boston's fashionable set has been coming here for years, which speaks to chef Jamie Mammano's consistently excellent French-Mediterranean cuisine with fail-safe favorites like tuna tartare, duck with cherries, and French Dover sole. The menu rarely changes—but no one's complaining. Unlike many trendy restaurants, Mistral sticks to what it does best. Brunch is served on Sunday.
