Had a hard time actually finding this place as I didn't know it was actually in the mall (go in where you see the TD, walk straight and take a right). Other than being in a pretty random location (definitely needs to be in like Square One or something) this is an awesome dessert place. I took my mother who literally has no sweet tooth but she even enjoyed it. We both got the ice cream rolls (mom got avocado, I got coconut) as well as the HK style waffles. The ice cream is super fresh tasting as you can taste the fruit that they directly mix in with the rolls which is different than places that just use flavoured liquid. I have also tried the sesame flavour which is also quite good. You get to also pick your own toppings for more customisation if that floats your boat.
Being a Chinese man, anytime I see HK waffles I will get them. These were fresh and steaming hot, not overly sweet. I would comment more but my nephews ate the whole two bags I bought so I couldn't really tell you. Overall, Wow Wow Yum Yum (despite its comical name) is a legit dessert joint. If you're in the area (but really why would you be around here???) definitely go check it out! Be prepared to wait a 5-10 minutes as they only have a few "grills" to make the ice cream rolls and waffles.
