I went solo in January and I ate at Marrakesh, Biergarten, Rainforest Cafe, Le Cellier, Rose & Crown, Sci-Fi, Mama Melrose,, House of Blues, and Crystal Palace for my sit down meals.
The only place I was uncomfortable was at the Biergarten. When they called my name, I walked in and was seated with a group of three men. Not wanting to be seem totally unfriendly I sat next to one. A few minutes later another group (also three men, but not with the first group) was seated on the other side of me. As the sole female at that table I don't know who was more uncomfortable me or them. Everytime one of them said a cuss word he'd get flustered and apologize and once one started what I guess was going to be an offcolor joke, when one of his friends elbowed him, then he got flustered and aplologized to me. It was really sort of funny. Anyway, I was just glad to get out of there and won't be going back solo.
