Located in Squirrel Hill, this place is very close to Razzy Fresh (frozen yoghurt), so it is always a toss up between the two. Sometimes the smell of fresh hot waffles draws me in to this place, but other times I am simply craving waffles and ice-cream. I fell in love with the waffles and ice-cream combo ever since I tried it a couple of years back in London and now I am hooked - I need my fix every so often.
Waffallonia makes the waffles to order (i.e. hot) and they have a decent assortment of ice-creams and fruits (vanilla ice-cream ans strawberries with a sugar waffle is the best combination IMO). They also have Nutella, chocolate sauce and some other toppings available.
The reason for the 4 stars is that the place is tiny (hardly any seating space inside), staffed with usually 2 people (waffles take long to make especially since they are to order) and that parking is always a pain (street parking). I usually go at night (around 9:30pm), which is when I can find parking easily and the rush is also less. However, I do rate this place as a must try if in the Squirrel Hill area or if you do not mind driving down.
