I work steps away from Rosebud and after 5 years decided to finally step inside. Have been there twice in less than a month, my new fav local restaurant! They are offering a $20 price fix 3 course meal, everyone I have gone with has had minimal complaints (the first time my friend said his duck was dry and last time someone didn't love the creme caramel).
The service isn't super fast but it's a small place and I can't see how they could possibly squeeze another staff member in there, just 2 working the front of the house works and they are very attentive.
It's been busy both times I have been there (once with no reservation and once with) and last time Neve Campbell was sitting at the table next to us.
