What to do about rehearsal dinner

It was brought up an idea to have our rehearsal dinner at Casabonita, We live in Colorado and if you have been to Colorado or seen South park we have a restaurant that is an experience to go there, that is about 20 minutes east of our venue, However, the food is horrible, Mexican food Tv dinners is a smidge better quality, My fiance and his family and most of our out of town family members who would be coming to the rehearsal has never eaten there and always says next time we are out we need to go to Casabonita, I don't mind going but I don't want food poisoning the day of my wedding, so I guess the question is do we just have the wedding rehearsal there knowing it has bad food or do we go somewhere else that has better food but not the experience,
