Along côte d'Abraham lies a small Asian restaurant, almost hidden but well worth a visit. The menu, which combines Thai, Vietnamese and Chinese cuisine, offers a nice selection of soups. Be especially adventurous and try the Thai tom yam, with crab and a very spicy broth that will unclog the most congested of noses.
A tip: dress lightly to eat at Thang Long! The tiny restaurant fills up quickly, offering, as a result, a warm atmosphere, not to mention the food alone is spicy enough to raise the temperature.
