Poor quality of food

Went to Mugg and Bean at the Ballito Junction Mall yesterday and had a sweetcorn fritter. Later on that day me and my boyfriend ended up with diarrhea. Unfortunately this is not the first time this has happend after having a meal at Mugg and Bean.Food standard and quality has definitely gone down.Each and every time I think would be better just makes me more dissapointed.Not happy with the quality of food!
