I love the food here, and it hits the spot every time. I usually order the chicken tikka masala with basmati rice, and a garlic naan on the side. The portions are reasonably large and the quality of the food is very good. The butter chicken also looks amazing.
I understand they have a lunch buffet here during the day, but I've never tried it so can't comment on its quality. The service can be quite slow and the food takes a long time to arrive, so if you're very hungry either get a starter to keep you going or order takeout.
Tip: There is a 15% off dinner coupon on their website.
