I've gone to Curry Twist a few times since I moved into the Junction back in June 2011. I've enjoyed it each time... which explains why I keep going back, hah! They often have a lineup to get in on Friday and Saturday nights, so keep that in mind if you want to go, especially if you've got a group of friends coming with you.
Service is friendly but not overbearing - they happily recommend dishes to order, amounts of rice to get, and all that, but they don't lurk near your table constantly either. Spice levels here are fairly mild, so if you're a spice fan, you might want to ask for your dish to be done hotter.
Favourite dish so far: the Baigan Bharta.
For the vegans out there: there are a number of vegan-friendly dishes on the menu, so you can stick this place on your roster of places to go with non-vegan friends and family.
