Houston-based Tiger Noodle House has opened a San Antonio spot with an extensive menu of Szechuan dishes, notably excellent pot stickers, a sublime spicy eggplant, and popular, pillowy xiaolongbao. Among the more exotic items: pork intestines Mao and numbing hot pots, including a frog leg version, wherein the skinny appendages are chopped into inch-long pieces before being crisp-fried.
