There are videos to this effect but I'm not a video maker or a research it all on my own-er. Off the top of my head:
-Peach and Bowser drink the victory champagne in the Japanese version of Super Mario Kart.
-Wario gets forcefed booze by penguins in the Japanese version (I get the feeling that qualifier will show up a lot) of Wario Land II
-Majora's Mask has Chateau Romani, the "vintage" milk that makes Gorman tipsy. And Young Link can have it too! Along with anyone else playable in both Smash and Hyrule Warriors Legends.
-One of the endings in Star Fox Command has Fox and Falco hanging out in a bar, but only Fox is clearly drinking.
-The Water of Life in Kid Icarus looks suspiciously red and comes in a suspiciously shaped glass.
-Sonic the Screen Saver includes a picture of Sonic drinking at Christmas. The videos I'm imitating in this thread tend to only count games even if other media is officially totally canon, but software included with a game might blur the line.
-Less blurry is that recent manga where Mega Man and his fellow Robot Masters are all grown up, and apparently there are alcoholic E-tanks. I'd check it out but then the nasty guy at UDON would have some of my money.
-Rounding out the "not a game" stuff for now is those videos what apparently say Isabelle likes whiskey.
-In the Japanese version of Earthbound, beating a drunk enemy might earn you an "Adult Drink".
-The Seventh Heaven bar is a moderately important place in FF7. I don't know if Cloud ever acts as a customer in the original, but apparently he does in the remake.
-One of the new score items in Pac-Man Plus is an unspecified purple drink in a wine-ish kind of glass with what appears to be a lemon slice on the rim.
-Castlevania Harmony of Despair has a couple of food items that seem like they'd have alcohol? That's why the thread title says "consumed" instead of "drunk". They include Steamed Mussel (mmmm, steamed clams!) which is described as follows: "White wine brings out the mussel's sweet flavor", so it's not clear if that's a statement that it's already being served that way, or a recommendation to have it that way. Then there's a tiramisu, and I'm pretty sure those are usually made with wine.
-Sans tends to be included in the videos that inspired this thread just because of his Mii Costume's infamy. I think the closest he gets is being a witness to Toriel's drunken antics (and not just in the deltarune continuity). He is a regular at Grillby's, but we don't know what "the usual" is for him when he isn't chugging ketchup.
-One of the unlockable images in Metroid Zero Mission shows Samus in a bar, but she looks like she's just there in search of intel.
That's a lot more than I was expecting to come up with but I've still barely scratched the surface. Peeps who know other games better than I do, please weigh in!
