So this is now the YWN Coffee LIQUOR room? A shonda! Yidden drinking low proof syrupy kid stuff :))))!
Seriously, Orlander’s on 13th Ave and 48th Street (4812 13th Ave) is the place to go for your Kahlua, because they have a nice selection at decent (but not the lowest) prices and the owner is very careful to tell you if something is not kosher. IIRC the Kahlua situation is also confusing because some is and some is not kosher.
And if you really want to try something with a kick, there is a hardware store a few doors down that carries paint remover, which everyone holds is kasher lemehadrin :))).
