On my monthly trip around the state of Arizona I tend to stay in Goodyear once a month.  I keep finding my way back to Rudy's.  They don't advertise gluten free but do have a lot of choices for any allergies.  Ask at the front desk they have a laminated allergy menu,  including dairy,  soy,  gluten and sulfites too.  Food is great.   I have tried the ribs,  sausages,  brisket,  potato salad and the cole slaw.  They have real food and always fill me up.  I have never been disappointed here.   I love the Chandler location too.   Will happily return.
