I got a lot of replies, although most were for grocery stores like Trader Joes or Whole Foods. Since I didn't have a microwave (or much time) I just ate at restaurants.
  What I did: 
  Tresca Restaurant at the Hyatt Hotel on Great America Pkwy. That was excellent and the chef prepared a special meal for me that was tasty and safe.
  Maggiano’s Little Italy, Santana Row: Asked at the host stand before I got seated and they confirmed they had GF pasta available. The chef came out and asked me what I wanted and basically prepared a special meal just for me. He also delivered it to my table so that I knew what I was getting. Very good experience.
  Village California Bistro, Santana Row: Showed my Triumph dining card and the chef came out and talked to me. I had the Seared Ahi salad which was wonderful.
  
  The responses:
  There are a few Whole Foods in the area, one is in Campbell off of Bascom Ave, but the only restaurant I have been to in San Jose is PF Changs and that is in downtown San Jose, close to South of Market.
  Thepthai, 23 North Market Street/Henry
  BoTown Chinese Restaurant
  House of Siam, Fairmont
  Maggiano's Little Italy, in Santana Row, gf pasta
