Not sure if you are still in Seattle but I eat out here all the time. I have multiple food allergies. A few places I have recently eaten at as a vegetarian with allergies, to tree nuts, peanuts, shellfish, and eggs include-
Din Tai Fung
Red Robin
Staple and Fancy
Cuoco
Cactus
Tutta Bella
Mamma Melina
Mandarin Chef
Shanik
Ivar's Salmon House
Chipotle
Also, would love to know the name of the Indian place you ate at successfully.
