Cake check: A good cake, as I point out frequently, is hard to find. Celebrity makes a decent divinity icing; Highland Park Cafeteria makes good chocolate cake. But Sweet Endings in Deep Ellum (or Plano) takes the cake. Their whole cakes start at $25 and they recently came up with a new flavor that makes waiting for dessert a good idea. The perfect summer cake: lime cake filled with lime curd, topped with lime buttercream, and garnished with fresh lime curls.
