answering Jonathan's question

There isn't a specific Laotian cuisine restaurant in London(the cuisine of the Lao ethnic group of Laos and Northeast Thailand)but you can find plenty of Thai cuisine restaurants,
Burmese you can find MANDALAY "Mandalay Burmese Restaurant" on 444,Edgware Road
Specialties are made with coconut, cumin, turmeric, dried shrimps, chili and lemon grass.I've asked our waiter which were the Burmese typical dishes, he explained;Coconut Noddle with Prawns,very subtle Coconut flavor, juice prawns and thick noodles topped with a crisp deep fried thin rice noodles, it also can be made with chicken or vegetables (vegetarian version)and Twice cooked Fish curry :it consists of a fine battered fish filled deep fried,topped with a "very spicy"tomato sauce were the favorites.
