We just tried out a new Thai restaurant on Pokrovka (about halfway down between Globus Gourmet and Pokrovskie Vorota, on the right, 'Tai'). It's been put where previously was the ZigZag.
Their menu shows pictures of all the dishes and levels of spicyness. Apart from the Thai name and one or two words indicating the type of meat or fish, there is no further description.
We were pleasantly surprised by the decoration, quite good and comfortable, primarily tables for 2 or 4. The prices are reasonable (although no business lunch), service for us was very quick. We chose a variety of soups and chicken, beef or pork dishes. Most of us liked spicy - so not just I the foreigner but all four of us enjoyed different levels of spicyness. Mine was a great, spicy mushroom soup; a colleague had a slightly less spicy mushroom coconutcream soup. My main dish - brought within minutes of receiving the soup - was just OK (beef) and not very spicy; one pork dish was especially flaming.
For lunch we ended up per person at approx 400-500 r each. Certainly we'll go back.
