Ah... the Happy Monkey.
Considering I can see them from my apartment window, and that they're a block from the office, I'm there at least a couple of times a month.
The decor? Industrial chic. Substantial wooden chairs and the bathrooms have "lost pet" note cards from all over the world (you need to see it to really understand).
The lunch specials are a little pricy, but you get a tremendous amount of food for the money. For $10.95, I can get a good portion of Panang Beef, two chicken satay skewers and rice. The barbecued pork and chicken lunch specials are also quite good.
For dinner, the prices are about the same as most upscale Thai restaurants - but the portions are about 50% larger.
