I really like the bagels at Moishe's on 2nd Ave between 6th & 7th. I don't know if they do wholesale, but their retail bagels are only 35 cents or something ridiculous like that. The Bagelry chain has good bagels. There's one on the corner of 14th & 7th. Also, Grey Dog's Coffee on Carmine St between Bleecker & 7th Ave South has good bagels. You could find out where they get theirs.
