I got three waffles (ube, cheese, and custard) for $5 and they taste fine. It's as you'd expect it to taste - a waffle with chosen taste in the centre.
The ube one was alright, nothing very special about it. I wished the cheese flavour had more cheese and was gooey or stringy. As for the custard, I probably enjoyed that one the most because it was runny as I had expected of the custard flavour.
I will probably be back to try the other flavours. Out of the three I tried, I would most recommend custard.
