Funny, I was about to post the exact opposite.
A really, really good Chinese is a superb meal, but they are so hard to find. Most are just sugary filled crap that all tastes the same. I can't remember the last good Chinese I had in Sussex. Are there any?
Where as a bang average curry is still perfectly decent.
I lived in Taiwan for three years and had a lot of 'proper' Chinese and local dishes like the incredibly fiery beef chilli noodle they do there that I finally managed to eat 'local style' after a few weeks of training.
For me the only place in Sussex I've found that comes close is Singapore Kitchen in Blatchington Road. Delivery still gets to you hot, it's not greasy, there are some good authentic dishes (Singapore Rice Noodles and Mapo Tofu) and they even managed to deliver salt and pepper squid from Blatchington Rd to Portslade and have it arrive hot, fairly crispy and not in any way rubbery.
Did also like an eat in Danny's before lock down. Apparently the two owners are related.
Every other Chinese I've had in the this country has been awful in comparison with the real thing but SK really hits the spot. Additionally amusing was being on the train to Norwich with @jackalbion on Saturday and discovering that both of our Friday night 'pre-match meals' had been a Singapore Kitchen delivery.
Here ends the advert. I have not been paid for this information.
I'm not fully au fait with the Sussex scene but there are few decent places in Brighton these days. From memory, Beijing House and CK Bistro (both Queen's Road) were decent when I visited. HK Place on Preston St too. I was going to mention Jia Mo for hand-pulled noodles but it seems they've closed down.
