You're likely referring to HungryPanda (熊猫外卖), which has carved out quite a niche in this and now operates across the US, Canada, Australia, Asia (outside China), Europe, etc.
I actually use this, I'm really into authentic Chinese food and some of the places aren't on the mainstream delivery apps but are on HungryPanda. The app is pretty bad but usable.
My Chinese-speaking friend told me that the business name translates to "rice balls". Fantuan appears to have a large presence in Anglophone countries such as AUS, CA, US.
And yes, any app that would be in the Chinese language is utterly weird and foreign to me. I can't even read or sound out the characters. I'd be more comfortable in a Hebrew or Arabic app, frankly. They would be "less weird" to me. Feel free to call me a racist bigot, but I'm an ordinary American.
