The restaurant formerly known as Thai Express received an upgrade of sorts when it moved from its strip-shopping-center location on Inwood Road to the new spot on Oak Lawn Avenue (underneath the offices at 3300 Oak Lawn Ave.) and re-branded itself as "Si Lom Thai Asian Fusion" in late 2012. While the menu offers a variety of scrumptious options, from curries, salads and noodles to the amazing pineapple fried rice and Thai classics like pad Thai, it's the tom kha soup that keeps us coming back time and time again. Si Lom's take on the lemon grass soup is made with coconut milk, cilantro, green onions, juicy hunks of tomato, straw mushrooms and a choice of chicken or shrimp. It comes served in individual portions or as huge, sharable platters, and diners are given a heat index to choose from. We recommend ordering the large and asking for it "hot."
