I have eaten at a few of these locations and they offer great food at a great price. I don't see why anyone would avoid eating at this restaurant no matter what the history. Especially since it's a change I think it's far removed from whatever past it may have had.
When people choose where to eat, they choose a place that has good food and an atmosphere that they feel comfortable in. Most people wouldn't care if the restaurant was run by a meth dealer. I personally wouldn't eat at it, but there are many people who would as long as the owner does not interfere with their food or service.
If anything, the restaurant's name is inspired by one from the TV series Breaking Bad and at most, it only throws a spotlight and makes it famous. It is my opinion that people will eat at a restaurant if the food served there is great and the service is adequate regardless of the name.
If the question is would people really not eat at the restaurant, I disagree. Yes, there may be less costumers for a while, but eventually people will forget about it and come back to the restaurant. Since the man is in custody there may not be any slowing of customers at all.
