I think there is quite a difference between a shot of sub-zero alcohol and a ingesting liquid nitrogen, which is at minimum -210°C vs the at most -70°C the alcohol will have, though likely the easier drinks will freeze at higher temperature anyway, usually starting at -5°C for a beer. edit: It also helps that ethanol is likely going to stay liquid in your stomach, liquid nitrogen boils off; that pulls a lot more energy from the environment.
