This is a non-descript group of souvenier shops that don't offer particularly much to do, though there is an arcade, miniature golf and a shooting game. Things seemed expensive and the food in the cafe was passable but not worth the money. Skip this one.
Unique Suggestions: Beers aren't too expensive, get drunk.
Fun Alternatives: The caves across the street are well worth the $8 admission.
There are locals who fit the Mark Twain image almost perfectly, so who can leave town without having the opportunity to meet Mark Twain? Unfortunately, at the time of our visit, the museum was closed.
