This was literally the last bowl before the stall closed so lucky me but at the same time I can't be sure it's the normal portion.

Nonetheless, it's absolutely delicious and ingenious. Mee Siam is sweet and sour, thus it makes perfect sense to add the sweetness and sourness of the fruits to it, which leveraging their aroma. It's very harmonious and not weird at all. Slurp worthy but I'm not a fan of sour food so I don't recommend adding the lime. Their chili is strongly tangy too, not very spicy.
