I went to Airstream Cafe in a group of six and had a great evening.
Staff were good and seemed relatively friendly. Food was good - I had a curry that was on the specials list and it was very nice. Hopefully its still on the specials list the next time!
The menu is very wide so would be enough options to cover everyones tastebuds.
The restaurant can become very 'barn-like', especially on Friday and Saturday nights and in turn be very noisy. In a goup of six, being able to hold a conversation became difficult at times.
