One of the best in the Chinese category and very authentic, is Han’s, located near the giant tower of the Hotel Olümpia. They are full on Chinese here, and offer many of the classics as well as many delightful spicy, yet full of flavour and delightfully spicy Szechuan cuisine. Interestingly, in China it is told that it's actually the food that makes the Szechuan women the most beautiful in the whole country. They have a truly huge selection of great dishes, even a decent amount of options for vegetarians and if you happen to be a fan or a foe of the spice, let them know how spicy you'd like it on a scale from 0-5 - they'll be happy to adjust the dish accordingly.
