Wish I had taken some pics as the current pics showing on the profile are outdated, Hai Tang has actually renovated and it looks little bit more modern, similar to "Phoenix Restaurant". Hai Tang gets a 4 from me not because it's fancy but it's crème de la crème out of the 'cha chang tangs'/HK café I've been too. Food is quite good and cheap, can get baked spaghetti/rice pork/chicken etc. for about $6 with a drink. Service is quick and not the typical rudeness from HK Cafés.
On the weekends and possibly on weekdays too, they have afternoon tea special which I believe starts at 230pm however if you go earlier they have some specials as well.
Just a word of warning, I guess after recent renos it hasn't gotten quite popular and there's typically a short 5-10 mins wait at times.
