Two old friends, chow-loving, from NYC/SF, visiting next week. One wants Indian, the spicier the better. The other will be tired from three days of grueling travel and work, but happy to have a rare kid-free, non-allergy-prone dinner (the son is deathly allergic to nuts and eggs so parents can't even eat those items when home).
So: Indian, spicy, warm ambience that's fancy enough to count as a Grownup Dinner but mellow enough to linger.
I was thinking Diva in Central Square, Rani in Brookline, or Tamarind Bay. Any votes or write-ins greatly appreciated. Thanks!
