## What kind of café is Wonz Coffee?

Wonz Coffee (ONESCOFFEE) is a café in Guui-dong, Seoul, near Children's Grand Park, and it takes its coffee seriously. The desserts are varied and the coffee is great to begin with, so it's already known as a neighborhood favorite in Guui-dong.

This is already my Nth visit! The inside is spacious and clean, so it's a good spot for a coffee and a chat. You can park about 2 cars beside the building, and it's about a 10-minute walk from Humun Station of Children's Grand Park. It's also a nice place to stop for coffee after a stroll through the park.

### A specialty local café with beans roasted by a national-team barista

Wonz Coffee is a specialty local café, and the coffee is brewed from beans roasted by a national-team barista, so the taste is a cut above. Great equipment plus great beans? It can't possibly taste bad!

There are also board games in a corner of the shop and an instant photo machine, so it's a good place to make memories too.

## How does the cold brew latte at Wonz Coffee come out?

The cold brew latte comes with the coffee concentrate in a separate beaker, and you pour it into the milk yourself. The cold brew is made in-house and sold there, and you can swap the milk for soy or oat.

Part of why I keep coming back is how kind the staff are. Even when it's busy they're always friendly and explain things well, so I leave in a good mood. And of course the coffee is the best! Even though I know nothing about coffee, I can tell the cold brew is good. It really feels different from other cafés.

Creamy milk meeting cold brew is wonderful. A perfect match with desserts! You just pour the concentrate from the beaker as you like, and I felt like a real barista.

### My husband's pick: Belgian handmade chocolate milk

The Belgian handmade chocolate milk my husband ordered has chocolate chips in it, so you get something to chew too. Because it's made in-house, the flavor is rich, with a sweetness that doesn't feel artificial.

## How do the plain scone and financiers taste?

Wonz Coffee is a baked-goods specialist, and its plain scone is best spread with the strawberry jam served alongside. It's a nutty scone full of butter flavor.

The salty choco financier is the textbook sweet-and-salty treat. Crisp outside, moist inside. It tastes like it's packed with almond flour, and it's really good. The macadamia financier is twice as nutty.

Wonz Coffee is a place where I eat well and chat happily every time I come. If you're looking for a café to recharge your sugar after Children's Grand Park, I gently recommend it.
