In the past 10 years, Thai food has become one of my favorite cuisines...sure its spicy and all but the flavor is fantastic.
I was introduced to this place, Siam Marina, 10 years ago by some good friends of mine. From the outside, this looks like a hole in the wall in the middle of a strip mall...but step inside and you hear New Age music on the stereo system and the ambience is perfect.
The food here is excellent. I've been to a number of Thai places in the Chicago area as well as in other cities, including in Oregon, and none compares to the what this place offers. Start off with Chicken Satay or Spring Rolls or even Shrimp on a Stick, get some hot and sour soup, and enjoy some drunken noodles or some Basil Fried Rice...or even duck...and top it off with some hot tea and if in the mood try one of their desserts....and the prices are not bad as well.
The only drawback to this place (and it might be an advantage because of the prices) is that its BYOB so make sure to plan for that. Otherwise, if you're looking for a great night out at a really neat place, try Siam Marina!
