If you want to eat quickly and good, and love asian food, that's your spot. At Chiang Mai, they have 4 different menus every day, going from Chicken Curry to Rabbit in thai sauce. Really good deal for the quantity and the quality of what you get.
For a quick and good lunch, Chiang Mai is definitely worth a visit. Plus, it's right between the main station and the north part of the Langstrasse. And you can buy some asian food items downstairs if you want to grab some noodles or coconut juice for cheap prices.
Ask for a khao niao mamuang, a dessert made from mango, and coconut rice. Awesome.
