Lab Sense ice cream is good! I'm not sure if it tastes any different because of the nitrogen (I sometimes think this just makes it look more dramatic and nothing else). That said, it does taste really creamy and some of the flavours are really good. My favourites are the tiramisu and strawberry cheesecake. Why only 3 stars then? Well it's a bit on the expensive side ($6.50), not all flavours are available all the time, and while it's good I've had better ice cream. That said, it's worth trying at least once, if just for the (smokey) experience.
