From what I know, if the business has a license, you can't take your own. If the business doesn't have a license, then you can take your own and there could be a corkage fee. If you have a good relationship with a restaurant and they know you're not Liquor Control, they will probably allow you to BYO for a special occasion. I don't think Columbus is a savvy enough wine market for a BYO model regardless. Back to your original post, as another poster commented, it might be how you're interpreting the code.
I'm a wine and beer enthusiast and I finished in the bottom half of my class. :)
You've gotten away from the original question. The original question is NOT "what can you do with BYOB in Ohio?". The original question is; Is BYOB not permitted in Ohio because of a direct statutory provision on point, or is it not permitted because the DoLC continues to repeat an incorrect (or correct) interpretation of a statute?". As should be abundantly clear by now, I suspect that the DoLC keeps repeating their own interpretation of a vague statute (centered on the word "keep") and perhaps their interpretation of the open container provision someone else posted above, and it seems clear that this interpretation has never been tested at the Ohio Appellate level.
