My sister and I are visiting the city for the first time and would like dinner ideas close to 2 plays we are seeing: Union Square Theatre and Golden at 252 W. 45th. Something relaxed and not stuffy or formal - ethnic is good. Can be moderately expensive.
Also, any places that would meet our criteria near E. 62nd St? I think it may be a little too ritzy up there for us. We're both pretty casual.
