Upstream has gone downhill, fast. While the bar ambience and feel is still awesome, the sushi in particular was extremely lacking. Spicy Tuna rolls were not fresh and smelled like fish. California rolls lacked flavor and were quite bland. \n\nService was also not particularly good and there was a very creepy manager who put us off. \n\nIt is a shame because Upstream has been a staple of the South Park area for years, but their sushi quality is completely lacking these days. I cannot comment on the main courses as we did not have any.
