A lid for a drinking cup enables drinking while inhibiting splashing and spilling. The lid features a dispensing well formed in a drinking spout. The dispensing well includes a plurality of openings in a sidewall proximate a spout front wall. All direct liquid paths out of the cup are substantially blocked. A plurality of baffles around the openings direct beverage flow in a plurality of channels before the beverage reaches the dispensing well. Beverage splashes larger than the channels are deflected or broken up, before passing through. The placement of the openings directs splashed liquid away from the user. A plurality of vent holes is provided to allow air to enter the cup as beverage is consumed. Vent holes located near the dispensing well can be blocked during drinking when the cup is full and the beverage is hot, but unblocked as the beverage cools and is consumed.
