The most recent time I went to RA, the hostess was MIA so I walked past the entrance and stood awkwardly at the bar for a few minutes. A girl whom I assumed to be the hostess walked by me and I smiled dumbly, hoping she would assume I needed help... but she smiled and kept walking. So I walked back to the hostess counter and stood there waiting for her to acknowledge me. Basically every time I go it's a version of this story.
The sushi is cheaper than Stingray and better than Sapporo, but I almost need to prepare myself for battle to just get a meal there.
