Janitzio on East Riverside is filled with the holiday spirit and doing very good business, including takeout. There were two tvs going, both without sound. I was facing Maribel Guardia in an infomercial for Caracol Cream, promising to rejuvenate the complexion. The jukebox was busy all the time at two plays for a dollar. We heard oldies, current Mexican pop, corridos of all types, and conjunto music. Janitzio today appeared to have more musician patrons than anybody else, but there were also singletons, family groups, and people who appeared to be construction workers on their day off. The red salsa that arrives with chips is addictive, with fresh tomato, lime juice, and black pepper flavors seeming to predominate. Extra tortillas of both kinds arrive with no need to ask for them. Mexican Coke with real cane sugar, not the corn fructose stuff, is available. At our table, we ordered chuletas de puerco in salsa verde, gilded from the grill, and excellent chile relleno. We saw other tables asking for repeat orders of campechana. Every stool was occupied at a small bar against the back wall. Janitzio shares a parking lot with Mariscos, at 1422 Town Creek Drive (telephone 442-6275). The Farm to Market Grocery on South Congress, where the conversation is livelier than ever on a holiday, was open all morning and on up until 3 this afternoon. I noticed that La Hacienda Market and Joy East Buffet are very, very busy today. BookPeople opened at noon and will stay open until 6 pm today. I love Austin’s small-town atmosphere on major holidays.
