I meet my buddies at the Ear Inn weekly for drinks and dinner. About once a month, after we've all met up and had a drink, the crowd looks to me for an alternative dinner venue. So far I've led the group to Walkers, Broome Street Bar, Molly's and Tavern on Jane.
All of these places have gone over well and share a similar vibe.
I'm running out of suggestions. Looking to add to my list. The only requirement (other than a good burger and a decent pint of Guinness) is the ability to seat a group of about ten and preferably located below 34th.
