Of the ones I haven't been to, none I wouldn't try. Of the ones I have been to (and in 10 solo trips, there've been lots of resturaunts), I wouldn't go back to anywhere with communal dining (where they sit you at tables with others). The one time I did that, I had a pretty bad time. I went to Teppenyaki and they sat me next to a teenaged girl (who was there with her family). The teenaged girl acted like getting seated next to me was her worst nightmare, and my attempts to ask her friendly questions about her trip were met with glares and monosyllabic grunts. Fortunately, I was a high school teacher, so I knew this was fairly typical and didn't take it personally. But the mealtime went by really slowly for me with no one to talk to (it was too loud to talk to anyone else at the table and I was on the end, so it was her or no one). I don't know which one of us was more relieved when the mealtime was over. But to my surprise, I've especially loved character meals. Great opportunity for people watching, and those people are so busy watching for the characters, you don't feel they're watching you.
