I'd highly recommend trying Vietnamese coffee. I'm the same way in that any coffee will do, but it's become my latest vice. It's a great middle ground between espresso (which I find a bit too strong) and drip/pour over coffee (which I like, but I prefer something a bit stronger). It's made with slightly compressed grounds in a phin (Vietnamese coffee filter) and is basically just a slower pour over that you mix with a tablespoon of sweetened condensed milk.

It's a very interesting flavor and tends to be much easier on your stomach because of the lower volume of coffee.
