The airport offers many restaurant ALL of which serve mostly meat! So I was glad to find this food booth that was willing to cater to my vegan request. The server understand English. I ordered a pad Thai and asked to leave out meats, fish sauce, and MSG (know in Japan by the brand name "Aginomoto"). To my surprise, the pad Thai was quite tasty and not too salty. Tofu was used as subsitute for meat.
Cons: serves meat
