Karim's serves up amazing food. It's big and busy, we had to share a table with other four Indian men and it ended up being more fun than if we had had our own table. Food comes quickly and everything is good.
I recommend any of the mutton dishes at Karim's, they are exceptional. Curries were good but not the highlight. I think it's best to keep it simple and go for tandoori or grilled meats. It's definitely worth a try if you're in the Jama Masjid area.
