I agree. The beauty of Tonx is that it's all about the coffee itself. No milk, no sugar, no dilution. Blue Bottle seems more about the coffee drink and less about the coffee
The Blue Bottle siphon bar in Chelsea (NYC) is a bit of a step back in the direction of "coffee itself". The brew methods are on the fancy side, but you can get the flight of two siphon coffees and compare the different qualities of the beans and such :)
