If you’re unfamiliar with hot pot, it’s a pretty simple concept: pick a broth, choose some meat and vegetables, then cook everything in a pot at your table. It’s a great group activity, and it’s similar to Korean barbecue - which you can also get at 99 Favor Taste. This is a chain with a few locations, including this one on St. Mark’s, which stays open until 2am every night. So if you hang late-night in the East Village, you might find this place useful for an after-midnight hang. The food is all-you-can-eat, and the cooking process should keep everyone in your group somewhat entertained.
