Vienna

Vegetasia -- is a super duper Chinese restaurant in Vienna. They serve not only dim sum but they have a full menu. This restaurant is very reasonable and totally vegetarian. It's amazingly delcious -- you'd never guess that it is not fish or meat. The restaurant is called Vegetasia, on Kaiserstrasse (near Burggasse) in the 7th district. Bon appetit,

I'm from Chicago but the best dim sum I've has been in London at Hakkasan. It's in the coolest location, tucked away down a side street and has phenomenal decor and food. It is by far my favorite. It's located at 8 Hanway Place, London W1P 9DH. Phone: 44 20 7907 1888. Email: mail@hakkasan.com. Enjoy!

I recommend a place called Dim T and they have three branches in London. I've been to the Charlotte Street one with my boyfriend to introduce him to dim sum and it was excellent. They have a selection of traditional pork and prawn type dim sum, as well as some adventurous new ones. And a bonus, chocolate dim sum for dessert! The branches are:
(1) 32 Charlotte Street London W1T 2NQ. Tel: 0207 637 1122
(2) 3 Heath Street London NW3 6TP. Tel: 0207 435 0024

Rome
Since 1979 Hang Zhou cooks real chinese dishes in Rome. With 50 seats and average prices of 15 euros, this restaurant is a friendly restaurant.

Tel: 06.4872732. P.S. This is the website, but unfortunately it is in Italian. Website: http://www.restaurantforyou.com/common/rist_it1047.html#
