You know what makes Karma 5 stars, Karma himself. That's the owner. He is open and sweet. He wants you to enjoy the food of his country and talks about his food with enthusiasm and joy. Karma is very proud of his homemade chilli sauce, so if you like spicy, do ask for it.
Now the food: we've been there three times and have always enjoyed our meals. I would say it is more so the delicious, clean home cooking, rather than amazing restaurant fare. It isn't greasy, msg laden, flavoured packed food. It is food you eat when you're tired of eating out. I've eaten here when I was too sick to cook. I ordered the steamed Momo, vegetarian noodle soup and some lentil/mung bean stew. All delicious.
