What part of town are you in?
If you are looking to pick up Opus and Tats, I would recommend the Tinderbox on Frantz Rd.
If you are looking for just Opus, go to Barclay, which is off of Sawmill Rd on Federated.
If you are looking for a good lounge to sit and enjoy your smoke, I would recommend Uptown Cigar Co in Westerville. Shawnee Cigar Co in Dublin has a nice lounge too, but I was in there on Saturday and the owner was kind of a prick to me and Flushnutz.
There are a few other B&Ms in town, and Flushnutz and I hit up most of them on Saturday. Seemed like a lot of shops had reduced the stock they were carrying in their humis. The shops I mentioned above were all fully stocked and definitely worth stopping by.
