This is a nice sit-down restaurant/bistro that is open till around 4am and serves very good food and drinks until closing. Go in for a shrimp cocktail, calamari, and other specialties with a nice glass of wine - not many other places can offer nicer food like that at such a late hour. The menu isn't huge but quality definitely comes before quantity. The service is professional and you don't feel like you're being rushed or overlooked just because it's late and the staff wants to go home, like at many establishments. It is also not as snooty as it can get on Rush St. so for a nice relaxing meal or late date definitely check out Bijan.
