Review of Slater's 50/50

My husband didn’t feel well after eating at this restaurant. They had to remake his burger even though we told them it was an allergy. The first burger came out with a regular bun even after ordering off of gf menu, then they were going to just replace the bun and serve again. Waitress did say they would remake when questioned and being reminded it was an allergy. I think it is a trendy place for gf but not really gf.
