Located in the front of the PAT supermarket, it's a tiny stall that basically sells fish waffles with various sweet fillings: 1.50-1.75 each
Red Bean
Black Bean (which has black sesame in it too)
Green Bean
Custard (new)
I liked the custard filling. The batter isn't that thick, so I don't think it's terribly unhealthy.
Good luck resisting temptation after you smell these on your way in to PAT..
