We checked out the Bangkok City on Mass. Ave. last night on the way to hear some music. The waiter was very helpful and was eager to educate us about what Thai people like himself would typically order and what he really liked. The real Thai menu is now located at the end of the regular menu.
Mrs. Edgeworth and I ordered 3 dishes for 2 people from the authentic Thai menu plus sticky rice and brown rice. After about 15 or 20 minutes or so and a Singha or two, all three dishes came at the same time and were clearly cooked to order. There was more than enough food.
The Chinese Broccoli with salty fish was a quite good and different. The salty fish seemed to be a fish paste that stays in small pieces and gets stir fried with the Chinese broccoli, a nice combination of flavors with a nice bite. The second dish was squid with chili paste. The squid was done perfectly and flavors were excellent. The third dish, crispy catfish, peanuts, .., was the most unusual. It was the waiters pick and I didnt catch the whole name. The catfish was shredded (almost like very delicate shredded wheat), super crispy, and not oily at all. There were lots of dry red chilis that had been stir fried, whole peanuts, cilantro, lettuce, lime juice, and other salad things.
The bottom line is we would definitely go back. I have never tried the Thai place 2 doors down, so I cant compare the two. For the three dishes we tried, I would say that the food was comparable in quality to Dok Bua, slightly more refined, and slightly more expensive. The total bill was $55.90 before tax and tip and included 2 beers and a glass of wine.
