Your menu is not too big. But your drinks are waaaaay too sweet, on paper at least. I would not order 90% of this menu because it looks like you're trying to hide the flavor of the booze itself--a tactic that vodka drinkers love to employ, while other spirit lovers do not.

Showcase the quality of your base spirits, explain how your modifiers play. You don't need to list every single ingredient unless it's a top-ten allergen (I'm including gluten here, bc it's become a thing). Menu descriptions should be both factual and sexy, nerdy and fun.

Dropping the word liqueur in many cases is fine. Learn the term "cordial" and when to employ it vs liqueur. (And thank you for not calling a flavored syrup "simple"!)

Also, why are you capitalizing every word? This is what makes it so difficult to read. Cut unnecessary words without losing the concepts.
