Awesome, glad to hear that. Quesadilla is also pretty popular indeed, I think the safest choice for coffee is definitely the soy, especially the one they use there is very smooth and "plain" (doesn't taste like soy at all for me), almond and rice are also good, they tent to make the coffee sweeter.
Just a friendly advice NEVER EVER USE COCONUT MILK, it simply doesn't work with coffee ;-)
