Recurring Upset Stomach Post-Coffee - Black Rock Coffee Bar, Mesa Arizona

5351 South Power Road, Mesa, 85212 Arizona, United States

I've given it about 4 chances now, and all four times I have gone to black rock, I've gotten a super upset stomach. I get something different everytime, but all coffee. Normally coffee doesn't bother my system at all but every time I drink black rock after finishing about half my drink I get hot, an upset stomach, and diarrhea. The drinks taste fine, and I haven ever had an issue like this at any other chain coffee place but something about Black Rock Coffee at this location really does a number on me. | Symptoms: Nausea, Diarrhea, Stomach Pain
