This is my favourite from the vegetarian stall at Tiong Bahru Food Court (Kopitiam), Tom Yam Soup, I like to order it with Guotiao. The soup base is good, it is sour enough though not as spicy enough for me. (It used to be my number 1 Tom Yam stall until I discovered Tom Yam Dry Thick Mee Hoon at Pine Tree Cafe, Fortune centre, introduced earlier which is both sour & spicyhttp://vegefoodhunt.blogspot.com/search/label/Tom%20Yam%20Dry%20Mee%20Hoon. The vegn fishes unlike at Toa Payoh HDB hub basement foodcourt are big slices & coated with a thin layer of flour & fried before adding to soup. Also nice in different way.
Sorry if picture did not turn up as appetising but Must try if you like Tom Yam !!!
