Snowfall cremas are interesting, drink + this salty thick white foam on top. Coffee iced snowfall was so good! The toast can be shared between 3-5 people depending on how hungry you are.
Try the beefdry noodles, as I heard it was best. Not many options, cheap, and cash only. You're served tea and given chopsticks. Might have to ask for anything else.
Wifi has been slow for the past few months, and the building seems to be a Faraday Cage for AT&T 4G. Head somewhere else if you need to conduct activities requiring fast Internet.
Parking is atrociously limited during weekdays until 6 PM. Unless you have a way of getting here that isn't driving, I suggest just not coming to this place during those times.
