We did both California Grill brunch and STK Brunch on our latest trip, on our upcoming trip we're going back to STK but didn't feel California Grill warranted a second visit, at least this time around.
From the start of Brunch up to 3:30pm on weekends is the only time you can order Frose (Rose bubbly and raspberry sorbet) at STK, it's quite good and one of the reasons we're going back, their "bag of donuts", cinnamon sugar monkey bread with cream cheese icing (brunch only), and the bacon appetizer which is now only available at Brunch were some of the best things we had the entire trip.
