The atmosphere at Nirvana is really fun, it has a great decor but is pretty relaxed. The staff are super cheery and helpful and they absolutely love talking about the food with you.
The smoothies are delicious (although a little overpriced for the size). They have great soups and I definitely recommend the falafel and the kale chips.
The food is clean, fresh and healthy. If you're looking for a mounding plate of food for a low price this is not for you, but if you're looking for something that will fill you up without weighing you down then you owe it to yourself to drop by Nirvana.
Cons: Very limited menu, Portions are a bit small
