Hey Doczoc, get out there and enjoy yourself mate!
Other than our local baked potato shop, I've yet to find an eaterie where you can't hunt and gather some great lowcarb nosh. You're right to be wary of a few Chinese dishes, but there should still be lots of others to enjoy.
There will surely be lots of meat and vegeable dishes (not the sweet'n'sour or battered things obviously) which are just as good without the rices and noodles. Foo Yung dishes are fine too - simply eggs, meat/fish/veg and nothing else. Some of the sauces, typically plum, satay, and pineapple come laden with sugars and are probably best avoided. Even so, there are still going to be more lowcarb do's than don'ts on a typical menu.
Don't let diabetes hold you back, go for it!
All the best,
fergus
