Leslie Cafe is a very cheap Western-style HK restaurant. They offer a wide variety of combos and specials. Their HK milk tea is one of the better ones that I've tasted. An interesting dish that you should try here is the ox tongue pasta (don't worry, it's a lot yummier than it sounds) as the meat is very tender and flavourful. Just be warned that there are times when this place is absolutely packed so as long as you're OK with loud Cantonese conversations going on around you, you won't have a problem. They also serve good Portuguese chicken here.
