Never judge a book by it's cover and in this case, never judge a restaurant by its name - in this case anyways. Neither truly Thai nor Californian, California Thai offers more of a fusion Canadian style fast, quasi-Chinese food.
I can't say the mango salad or the curries are remarkable or outstanding but I have more often than I care to admit ordered the beef ho fan and the Singapore curry fried noodles. The general tso is also pretty good and the salt and pepper squid/seafood another often ordered item. While I can't say everything is the best, it's close, you get a lot for what you pay and it satisfies.
