I keep forgetting the answer to this question, so I'm going to post it here so I won't forget.
Muligatawny is on Monday and Thursday according to our awesome server last night. She also said the recipe has changed a bit from when I was there last and it isn't as creamy anymore, but she said it was still good.
It's okay anyway because the Lentil and Sausage soup may be my favorite now.
