BrickTop's

BrickTop's is the brunch anchor of Plaza Frontenac whose Sunday brunch from 10 a.m. draws regulars from across the St. Louis area. The menu covers what a well-executed American kitchen does best: deviled eggs with million dollar bacon, lobster bisque, sesame-seared ahi tuna, crab cakes, and a Tavern burger that regulars return for specifically. The patio is a genuine asset when the weather cooperates, and the room inside has the upscale-casual character that suits everything from a birthday brunch to a relaxed Sunday with family.

Why BrickTop's Works for Brunch

  • Reservations available and recommended for Sunday brunch

Mariposa at Neiman Marcus

Mariposa, on the second floor of Neiman Marcus at Plaza Frontenac, is one of the most distinctive midday dining experiences in the St. Louis area. Walk through the shoe boutique on the second level and step into a refined, art-filled dining room with an umbrella-shaded outdoor patio and service that consistently draws the warmest reviews in the Frontenac dining scene. The famous popovers are mandatory, and the Mandarin Orange Soufflé has its own dedicated following. Champagne and fine wine are available alongside excellent coffee, and the Garden Room can be reserved for private events.

Why Mariposa Is Worth Seeking Out

  • A refined second-floor dining room inside Neiman Marcus at Plaza Frontenac
  • A menu of crab cakes, salmon, strawberry chicken, and generous salads, anchored by the famous popovers and the legendary Mandarin Orange Soufflé that regulars plan visits around
  • An umbrella-shaded outdoor patio and an art-filled interior that create a pleasant mid-morning or lunchtime atmosphere
  • Open Tuesday through Saturday, 11 a.m. to 3 p.m.

Brio Italian Grille

Brio at Plaza Frontenac brings a Tuscan-inspired Italian kitchen to the brunch conversation, and its Sunday brunch has earned consistent praise. Guests highlight Berries and French Toast as a standout, and the broader menu of premium steaks, made-to-order pastas, flatbreads, and seafood gives Brio depth that suits both a full group brunch and a quick midday meal. Service earns consistently strong marks, and the ambiance reflects the comfortable sophistication that characterizes Frontenac's dining scene.

Why Brio Works for Sunday Brunch

  • A Tuscan-inspired Italian brunch menu with standout dishes including Berries and French Toast, in a polished dining room at Plaza Frontenac that suits both casual Sunday mornings and celebratory group meals
  • A broader menu depth that gives Brio options for every appetite at the brunch table
  • Consistently praised service and a comfortable, sophisticated ambiance that reflect the quality of the broader Plaza Frontenac dining environment
  • Reservations available and recommended for Sunday brunch service

Companion

Companion, the artisan bakery and café near the edge of Frontenac, is not a brunch restaurant in the conventional sense, but for residents who prefer their weekend morning to start with excellent coffee and a perfectly made croissant, it is the first stop. The café serves breakfast and lunch with house-made pastries, gourmet sandwiches, and fresh salads, produced with the ingredient quality and craftsmanship that has made Companion one of the most beloved bakeries in the St. Louis area. The space is cozy and welcoming in a way that invites lingering, and the morning crowd reflects the neighborhood. For an early weekend morning before the day begins, Companion is consistently the right answer.

Why Companion Is the Right Morning Start

  • Artisan breads, house-made pastries, and croissants that are among the best available in the Frontenac and broader St. Louis area
  • A breakfast and lunch menu with gourmet sandwiches and fresh salads that extends well beyond the pastry case for residents looking for a more complete morning meal
  • A cozy, welcoming atmosphere that draws a loyal neighborhood following and makes Companion a natural gathering point for Frontenac residents on weekend mornings
  • A relaxed pace and friendly service that make Companion the ideal starting point for a Saturday or Sunday before the rest of the day takes over
