Tum Nak has so many good reviews and they deserve every one!  Far east Mesa can't be the best location for a place like this, but they seem to keep customers coming back (I definitely do anyway!).

The Yellow Curry (hot) is my favorite, but I've tried just about everything on their menu and I've never been disappointed.

The only negative is that the place is super small, so as the popularity gains, the more I find myself ordering to go :)
