Not really a cafe, this bustling breakfast stop serves kôw đôm (rice soup), gŏo·ay đĕe·o (noodle soup), kài gà·tá (pan egg with sausage) and traditional Thai coffee. The service is lightning-fast, and it's a great local experience. No English sign, but there's a clear, well-translated English menu.
