I live nearby, and I visit Thai Chili every couple of weeks. The staff are polite, friendly and fast, the food is reasonably priced, tasty, and if you ask nicely, hot enough to melt your brain. A 6/10 is noticeably spiced, an 8/10 will leave your lips tingling for the better part of an hour, and I've never been brave enough to ask for a 10/10.
Their daily specials are good. If you get a chance, try the steamed white fish with ginger, mushrooms and green onions. Very good stuff.
