Reviews Summary

The Sister Cafe Upstairs offers a unique dining experience with a strong focus on vegan and gluten-free options, particularly its waffles. While many praise the creative ambiance and dietary inclusivity, some reviews point to inconsistencies in food quality and value for money. It's a spot that shines for its atmosphere and specific dietary offerings, but experiences can vary.

"Hit and miss. Some of the food was good and some was not. We had to add salt and pepper to almost everything.

The salad and the sandwich was tasty. Everything else needed improving on many levels.

Falafel were too dry, crumbly and not really edible. They did not charge us for them which was nice.

The decor is nice and ambient. The staff are friendly."

Kartik Shah

"It was great to find somewhere to eat where I didn't have to read the small print on the menu! I'm gluten and lactose free so finding anything to eat in Brussels was a nightmare, apart from here. We had breakfast here both days and I loved everything I ordered!
It wasn't the cheapest place, but it was worth it to get something 'safe' to eat."

Tricia Peters

"So delicious I came back 3 different times on my short trip in Belgium. The waffles, the breakfast plates, the soups, juices and sandwiches are dishes I still dream about here in San Francisco. I would go back to Brussels just to eat at Sister Cafe again. 100/10, no notes, an absolute must try."
