Great find from the fly-over zone!
St. Louis has two major asian communities, one in University City, where I live, and one in the City of St. Louis on Grand Blvd. and environs. At 4071 Grand there is a sign that has the #1 and the words Banh Mi So (translation, #1 sandwich.) Great Vietnamese pork meatball sandwiches and celestial spring rolls. The latter come in shrimp and vegetarian, made while you wait. If you live in St. Louis, definitely GO. If you are planning to visit, email me and I'll take you there. pat
